Paleobiota of the Ciechocinek Formation

The Ciechocinek Formation is a Jurassic (lower to middle Toarcian) geologic formation which extends across the Baltic coast from Grimmen, Germany, to Nida, Lithuania, with its major sequence in Poland and boreholes in Kaliningrad. Dinosaur species uncovered here include the Thyreorporan Emausaurus and others with an unclassified genus.

Terrestrial environment of Łęczna (Lublin, Poland), based on Bogdanka Coal Mine flora. Dinosaurs are based on material found in the formation.

In Poland, the main basin lacks marine microfauna. The Ciechocinek Formation in the Częstochowa-Zawiercie area reveals the remains of a wide range of prehistoric environments; the Fore-Sudetic Monocline region must have been an extensive bay similar to Lake Maracaibo in Venezuela. The basin's shore zone was a flat, muddy, marshy coastal plain.

The region has the remains of the Wrêczyca River, which was active for most of the Pliensbachian/Toarcian period. At the Brody-Lubienia borehole (Lubienia), which once formed part of the river's east side, an alluvial system ended at a delta and discharged into a shallow marine bay and lagoon. A number of phyllopods and fossilized plant roots have been found here, where they were discharged by the river. Paleosol indicates that the lagoon had a maximum depth of about 6 metres (20 ft).

Xylophagous Fungi[11]

  • Morphotype A (Aseptae)
  • Morphotype B (Sphaerical)
  • Morphotype C (Sack-shaped)
  • Morphotype D (Transverse septa)
  • Brody-Lubienia borehole.[11]
  • Gorzów Wielkopolski Borehole
  • Mechowo Borehole
  • Parkoszowice borehole
  • Fungal Spores
  • Hyphae-like attachments

Saprophyte fungal Spores from Marine and Deltaic Settings associated with wood and Litter.[11] The frequency of fungal spores on the Polish basin on the Pliensbachian-Toarcian transition is correlated with negative C isotope peaks and enhanced cuticular plant litter accumulation, pointing to the climate-driven enhanced decomposition of wood and rapid destruction of terrestrial carbon, which may have played an important role in the aggravation of the Jurassic Greenhouse disaster.[11] Associated with a high rate of organic burial, the presence of Fungal Matter increased on the Uppermost layers of the Drzewica Formation, with a continued deposition between the T-OAE extinction, and several ups and downs on the Ciechocinek Formation, related with local climate and humidity changes. This is rather a reflection of the efficiency of terrestrial biodegradation.[11] Measured increasing of temperature favored local fungal-mediated decomposition of plant litter, specifically of normally resistant wood.[11] Observed fungal spores represent various morphotypes and resemble superficially other palynogenic detritus, such as spherical Prasinophyceae.[11] In some cases spherical fungal spores show structures related to Hyphae attachments.[11]

Spores found on the Polish are mostly from Saprophyte (wood decomposers) fungi, resembling the extant genera like Scutellinia, which are probably the main origin for the Fungal Spores found on the Ciechocinek Formation

Amerospores[11]

  • Morphotype E (Amerospore)
  • Brody-Lubienia borehole.[11]
  • Gorzów Wielkopolski Borehole
  • Mechowo Borehole
  • Parkoszowice borehole

Fungal Spores

A Saprophyte fungus, member of the family Sordariomycetes inside Ascomycota.[11] Non-filamentous spores with no septations and with no projections longer than the spore body. Related with the extant genus Poronia. Fungal spore peaks linked to a relative and absolute loss of wood suggest a prominent role of fungal wood decomposers.[11]

Poronia punctata, an extant saprophyte fungus with Amerospores. Similar fungi probably liberated this spores on the Ciechocinek Formation

Phragmospores[11]

  • Morphotype F (Phragmospores)
  • Brody-Lubienia borehole.[11]
  • Gorzów Wielkopolski Borehole
  • Mechowo Borehole
  • Parkoszowice borehole

Fungal Spores

A Saprophyte fungus, member of the family Dothideomycetes or Sordariomycetes inside Ascomycota.[11] Spores with two or more transverse septa. Related with the extant genus Acanthostigma, facultative pathogen, or beneficial partner of many plant species. Local humidity, though sufficiently high for fungal development throughout the whole T-OAE interval, is therefore thought to have been of a lesser significance for dynamics of fungal decomposition than elevated temperature.[11]

Leptosphaeria acuta, an extant wood fungus with phragmospores

Dictyosporiaceae[11]

  • Morphotype G (Dictyospores)
  • Brody-Lubienia borehole.[11]
  • Gorzów Wielkopolski Borehole

Taenidium[13][14]

  • Taenidium serpentinum
  • Dobbertin Clay Pit

Unlined meniscate burrows

Saltwater/Blackish burrow-like ichnofossils. Taenidium is a meniscate backfill structure, usually considered to be produced by an animal progressing axially through the sediment and depositing alternating packets of differently constituted sediment behind it as it moves forward.

Chondrites[13][14]

  • Chondrites bollensis
  • Dobbertin Clay Pit

Small branching burrows

Saltwater/Blackish burrow-like ichnofossils. Interpreted as the feeding burrow of a sediment-ingesting animal.[15] A more recent study has found that Scoloplos armiger and Heteromastus filiformis, occurring in the German Wadden Sea in the lower parts of tidal flats, make burrows that are homonymous with numerous trace fossils of the ichnogenus.[16]

Planolites[17]

  • Planolites montanus
  • Planolites beverleyensis
  • Kozłowice Clay Pit
  • "Boroszów" Brickyard

Cylindrical or elliptical curved/tortuous trace fossils

Saltwater/Blackish burrow-like ichnofossils. Planolites is really common in all types of the Ciechocinek Formation deposits. It is referred to vermiform deposit-feeders, mainly Polychaetes, producing active Fodinichnia. It is controversial, since is considered a strictly a junior synonym of Palaeophycus.[18]

Helminthopsis[17]

  • Helminthopsis isp.
  • Kozłowice Clay Pit
  • "Boroszów" Brickyard

Simple, unbranched, horizontal cylinder traces

Saltwater/Blackish burrow-like ichnofossils. There are a few specimens in the Kozlowice outcrop. It is interpreted as a grazing trail or Fodinichnia, produced at shallow depth in sediment by Polychaetes and Priapulids.[17]

Example of Helminthopsis fossil

Gyrochorte[17]

  • Gyrochorte isp.
  • Kozłowice Clay Pit
  • "Boroszów" Brickyard

Winding, horizontal, double ridge burrows, separated by a median groove.

Saltwater/Blackish burrow-like ichnofossils. On the Kozlowice strata, only a few specimens were observed. Gyrochorte is interpreted as a result of active digging on the sediment by a deposit-feeding worm-like animal, probably Annelid or similar kinds of creatures.[17] Some modern species such as the Polychaete Pectinaria and some Scaphopoda mollusks let similar traces on the sand. Is a genus fond mostly on moderate to moderately high energy environments, including bars, shorefaces of beach complexes, storm-dominated shelves, and embayment areas?[19]

Protovirgularia[17]

  • Protovirgularia isp.
  • Kozłowice Clay Pit
  • "Boroszów" Brickyard

  • Kozłowice Clay Pit
  • "Boroszów" Brickyard
  • Pawłowice 40 Borehole

Horizontal and subhorizontal, branching tunnels,cylindrical or elliptical in cross-section, displaying elongated striation on exterior of burrow casts

Saltwater/Blackish burrow-like ichnofossils. On the Kozłowice section a series of sand-filled tunnels of Spongeliomorpha are preserved as Endichnia within mudstone, preserved as Tubular Tempestites (Storm-burrow filling), open tubes produced by animals burrowing in a stable, stiff or firm sub strate.[20] Here the tubes occur in one ho rizon with thin sandy laminae and lenses that represent isolated Starved Ripples carried on the muddy sea-floor by storm-generated Traction power network.[20]Spongeliomorpha is believed to come from the domicile of Crustaceans: Anomuras (Probably Eocarcinoidea) and Decapodas (Probably Glypheidae), created as they dig in a firm, semiconsolidated substrate.[17] Local Spongeliomorpha could point to a transgressional Sea water impulse following a short episode of regression.[17]

Teichichnus[21]

  • Teichichnus isp.
  • Gorzów Wielkopolski IG 1 borehole

Vertical to oblique, unbranched or branched, elongated to arcuate spreite burrow

Saltwater/Blackish burrow-like ichnofossils. Is common on the Pomerania Region. The overall morphology and details of the burrows, in comparison with modern analogues and neoichnological experiments, suggest Echiurans (spoon worms) or Holothurians (sea cucumbers) with a combined suspension- and deposit-feeding behaviour as potential producers.

Cocoons

Freshwater Clitellata Cocoons (Oligochaeta and Hirudinea), identified with palynological residues, and through to be tridimensional nets of probable algal origin.[25] Fragmentary mesh-like networks of happiness threads composed of homogenous translucent material. They show the outer wall (hapsine) construction specific to clitellate annelids and lack an alytine (inner) layer. A disorderly meshwork of the hapsine layer and hapsine fibers of unequal thickness, are diagnostic of the type species Dictyothylakos pesslerae. The cocoons Dictyothylakos pesslerae resemble specially those of modern Leechs, and are common on flooded basin sediments, which implies not only the presence of parasitic leeches, but also the presence of large hosts nearby, as has been confirmed on the case of the Ciechocinek Formation, thanks to the presence of not only dinosaurs but also Dipnoi and other freshwater taxa.

Cunchs

A Freshwater Clam shrimp (Phyllopodan) of the family Lioestheriidae. They fed on detritus, being very small slow moving, nektonic organisms that filter fed as they floated. The specimens are numerous here and form thin layers, being the most abundant invertebrate recovered on all the formation. The presence of Palaeestheria marks the appearance of less saline conditions, as this is a mostly freshwater genus. The local Phyllopods are related with a great amount of freshwater debris (especially plants), and suggest seasonal changes on the rivers on the Toarcian Polish Basin. On Kozłowice, there is an association of the ichnogenus Planolites and phyllopods of this genus, which reflects a gradual decline in water salinity during a sea level high standard regression.

Single Incomplete Specimen.

A spider, possible member of the superfamily Palpimanoidea.[71] It is the first confirmed spider from the lower Jurassic, and a rare find, probably washed to the sea due to a hard wind related to hurricane action, present due to the measured monsoonal conditions of the formation, as on the rest of the Lower-Middle Toarcian strata. Probably a ground-dwelling predator that hunted the abundant insect fauna present on the layers.[71] With a robust and well-armed legs I, directed forwards give the suggestion that they were preycapture appendages, a morphology typical of a sit-and-wait predator, while the short legs III are more typical on web spiders, especially Orbweavers, but also found on Palpimanoids, but not on that that are common substrate dwellers, that had legs more equal.[71] Seppo was probably not a habitual ground dweller, with armoured front legs related to capturing dangerous prey, such as many palpimanoids today are Araneophagous, for example.[71]

Freshwater/Brackish/Marine Osteichthyes, incertade sedis inside Teleostei. Inconclusive remains of fish (mostly teeth) are found mostly on Częstochowa-Wieluń region. The Remains of fish are rather rare on the Polish Realm of the Formation, and found related with the Silesian coast, where embayments and lagoons were formed. The remains were not compared. The lack of typical marine fauna indicates that the Toarcian sea transgression did not cause the development of normal-marine conditions in the Polish Basin. "Type A" and "Type B" includes fragmentary remains that resemble the genera Dapedium and andya, with rounded teeth. "Type C" is more similar to the genus Ptycholepis. Finally, "Type D" & "Type E" resemble the Amiiformes and Osteoglossiformes.

Evidence of wildfires increases in the upper part of the formation.

The Łęka Coal Basin has been known since 1800 for its abundant deposits; younger material has been suggested as redeposited from the Paleozoic, but the basin primarily yields a series of Pliensbachian-Toarcian coals.[143] In the Early Jurassic the Blanowice Formation was surrounded by land on the north, east and south, the source of sediment which was deposited as nearshore coal.[143][144] This coal is abundant in the upper part of the formation, dominated by alluvial and lacustrine sand and coal-bearing sediments.[145] Organic matter associated with the coal includes the oldest known biomolecules (in the Mrzygłód clay-pit), composed of labdanoic acid, ferruginol, sugiol and 7-oxototarol.[145] The extracted samples were recovered at the Wysoka Lelowska 47Ż and Jaworznik 124Ż boreholes; five core samples were taken from the Żarki 90Ż core, the latter from an approximately 1.5-metre (4 ft 11 in) coal seam.[145] The random reflectance (%Rr) of the coals is 0.47–0.56, indicating sub-bituminous coal.[145] The geochemical data suggest low-maturity sediments,[145] and hopane isomers are relatively high in all samples.[145] This is confirmed by unstable biomolecules in the coal samples, including labdanoic acid, ferruginol, sugiol, oxototarol, beta-sitosterol and cholesterol.[145]

The coals are generally dominated by vitrinite macerals, except for a high percentage of inertinite. This indicates wildfires or peat fires, confirmed by charcoal fragments.[145] Sesquiterpenes and diterpenes, common in conifers, angiosperms and bryophytes, were also recovered from the coal.[146] Vitrinite has a reflectance value of 0.49-0.56 %Ro. The cupressaceae and podocarpaceae families are considered the main peat-forming plant species, due to the presence of phenolic abietanes and dehydroabietic acids.[145] Lignite indicates significant benzohopane derivatives in the surrounding sandstones, probable differences in biodegradation, and a typically-low coalification range.[147] Later, larger studies note the influence of fires on the region.[148]

The Kaszewy coals, found in an approximately 150-metre (490 ft) section of terrestrial and marine siliciclastic sediments in the Kaszewy-1 and Niekłan PIG-1 boreholes, are the Ciechocinek Formation's major coals.[148] This section was in a nearshore-deltaic setting, with increased terrestrial and marine organic matter reflecting increased weathering and transport of terrestrial matter.[148] Abundant fossil charcoal and polycyclic aromatic hydrocarbons have been found. The number of coarse fossil charcoal particles (larger than 125 micrometers) in the Pliensbachian-Toarcian sections of the Kaszewy-1 core is very low (0-15 particles/10 g sediment), and fine charcoal particles (<125 μm) are more abundant (~12,000–256,000 particles/10 g sediment); there are also more non-charcoal particles.[148] There are more fine charcoal particles at the beginning of the Toarcian, reflecting environmental changes. In the polycyclic aromatic hydrocarbons, the pyrolytics (benz-anthracene, benzo(k)fluoranthene, fluoranthene, indeno[1,2,3-cd]pyrene, phenanthrene and pyrene) were detected in a wide variety of samples; phenanthrene is the most abundant component and coronene the least, suggesting the burning of organic matter.[148] Petrogenics are more abundant on the coal samples than pyrolytics, suggesting low wildfire activity.[148] Although the Kaszewy-1 borehole did not indicate increased wildfire activity, the fine fossil-charcoal abundance and pyrolytic concentration indicate regional wildfires.[148] Pyrolytics indicating the increased wildfire activity match the beginning of the Toarcian anoxic event, with intervals of fewer wildfires.[148] Wildfire changes match the Lower Toarcian negative carbon-isotopes emissions measured on the, which probably promoted a rise in atmospheric oxygen. Some questions remain; the climate was warmer and wetter (which can suppress wildfire activity), and wildfires persisted in the Kazewy-1 borehole wildfire activity was successfully sustained.[148] Wildfires may have subsided due to a lack of suitable fuel.[148]

Megaspores

Polish Lower Toarcian palynology is assigned to the Paxillitriletes phyllicus (Ph) level (Isoetales), due to the abundance of this genus.[149] The lower part of the Toarcian level has numerous occurrences of this species, sometimes before the genera Erlansonisporites sparassis (Selaginella-like) and Minerisporites volucris (Isoetaceae) in the Gorzów Wlkp. IG 1 borehole.[149] The upper part contains less of the genus.[149] The most common species found on Poland in this era include Erlansonisporites sparassis, E. excavatus, Minerisporites volucris and Biharisporites scaber (Lycopodiopsida); Aneuletes potera and Trileites murrayi (both Selaginella) are found on the upper levels.[149] The Toarcian disturbance of the carbon cycle recorded on the Ciechocinek Formation, coincides roughly with the appearance of Paxillitriletes phyllicus. The type of dominant palynomorphs recovered changed from pollen grains during the Upper Pliensbachian to megaspores, indicating a climatic change from moderate and relatively dry to warm and humid in the early Toarcian.[149] This shift in local climate correlates with a global maritime transgression in which volcanism in the Karoo-Ferrar large igneous provinces raised the global temperature and disrupted the carbon cycle, creating a major greenhouse effect.[149] The prevalence of megaspore Paxillitriletes phyllicus correlate with warmth and humidity; the flora, dominated by the family Isoetaceae, requires standing water to reproduce.[149] The megaespore Paxillitriletes phyllicus then drops significantly, indicating a return to a more moderate climate during sedimentation of the younger Borucice Formation.[149]

Megaflora

The Lublin upland fluvial sandstones contain diverse fossil flora, associated genera and species with Lower Jurassic sediments. Carboniferous flora, similar to that of Jurassic formations, appeared in boreholes near the planned Bogdanka Coal Mine.[171] The age of the plant material was not determined until 2020, when it was identified as Lower Toarcian (with some Late Pliensbachian strata).[172] The Brody-Lubienia borehole is abundant in terrestrial palynomorphs and aquatic biomass.[172] The sediments from Brody-Lubienia have a more-terrestrial character, indicated by the frequent occurrence of plant roots and paleosol horizons;[172] moisture was probably fresh (not saline) water.[172] The environment was probably dry, developing flora near freshwater inflow from the east.[172]

The Lublin lias is dominated by cycads and Bennetites Ginkgoales. Ferns occur sporadically in the bottom of the Toarcian, where deposits are filled with coal, mudstone, sandstone and clay siderite (reworked from the Carboniferous) and pebbles from Devonian limestones.[173] Similar boreholes and nearby deposits indicate the end of a river which transported Devonian-Carboniferous deposits from the northeast to the aquatic inland environment.[173] Vegetation grew primarily outside the sedimentation area, on shores and in shallow water.[174]
