	Rotzo Formation (Italy)

The Rotzo Formation is a geological formation in Italy, dating to roughly between 189 and 183 million years ago and covering the Pliensbachian stage of the Jurassic Period in the Mesozoic Era.[2] Has been traditionally classified as a Sinemurian-Pliensbachian Formation, but a large and detailed dataset of isotopic ¹³C and ⁸⁷Sr/⁸⁶Sr data, estimated the Rotzo Formation to span only over the whole Pliensbachian.[3]

Fossil prosauropod tracks have been reported from the formation.[4] This formation was deposited within a tropical lagoon environment which was protected by oolitic shoals and bars from the open deep sea located to the east (Belluno Basin) and towards the west (Lombardia Basin). It is characterized by a rich paleontological content. It is notable mostly thanks to its great amount of big aberrant bivalves, among which is the genus Lithiotis, described in the second half of the nineteenth century. The unusual shape of Lithiotis and Cochlearites shells, extremely elongated and narrow, characterized by a spoon-like body space placed in a high position, rarely preserved, seems to suggest their adaptation to soft and muddy bottoms with a high sedimentation rate.[5] The Bellori outcrop displays about 20 m of limestones with intercalated clays and marls rich in organic matter and sometimés fossil wood (coal) and amber. The limestones are well stratified, with beds 10 cm to more than one metre thick, whereas the clayey levels range between 3 and 40 cm in thickness.[6][7]

Invertebrata

Microfossils of the Rotzo Formation consist of benthic foraminifera, calcareous algae, Ostracoda and coprolites. Foraminifera are mainly benthic agglutinated species belonging to the superfamily Lituolacea (suborder Textulariina), while lamellar and porcellaneous-walled species are very rare.[8] The bivalve Opisoma excavatum is very common.[9]

Ichnofossils

In the Western Venetian Prealps a shallow-water, oceanic carbonate platform system, the Trento platform, developed on the Early Jurassic, producing a large succession of massive to well-bedded white Limestones, several 100 m thick that are part of the Calcari Grigi Group, where the Rotzo Formation is the Upper Member.[10] On the local limestone of the Rotzo Formation deep burrowing is a very common type of biogenic activity, as is shown due to the presence of a large characteristic network of burrows which reach down to the lagoonal, marly-clayey assigned strata, suggesting intense bioturbation by large unknown organisms, perhaps giant decapod crustaceans (Probably members of the family Erymidae), although, the burrows found aren't closely related to the ones of Shrimps or other decapods, but resemble those of Stomatopoda and Malacostraca.[10] Other includes abandoned burrows, vertical biogenic action and infilling on the sea substrate.[10]

Thalassinoides[11][12][13][10][14]	Thalassinoides suevicus Thalassinoides? isp. B	Campomolon, Valbona	Burrowing and track Ichnofossils	Thalassinoides suevicus has been found on mostly of the middle-upper part of the Rotzo Formation associated with muddy deposits. It ranges from 2–5 cm to 6–10 cm and the larger ones from 10–16 cm.[11] Y-shaped tunnels that seen in cross-section reveal circular walls made of pelletoidal grainstone, being more probably a fodichnia of a burrowing animal.[13] A few ichnofossils include simple cylindrical tubes up to 80 cm in length, that resemble crustacean described in Seychelles.[13]	Thalassinoides

B	Campomolon, Valbona	Burrowing and track Ichnofossils	Two major types of Ophiomorpha where recovered, a smaller one from 2–4 cm in size and the larger one from 5–15 cm in diameter.[13] They are complex burrow systems lined with pelletoidal sediments generally infilled by coarse-grained detritus.[11] isp. A seem partly destroyed by weathering.[12]	Ophiomorpha

Very narrow, vertical or subvertical, slightly winding unlined shafts filled with mud. Locally, post hurricane burrows are found in fine-grained tempestite beds and muddy layers and they are Domichnia, Fodinichnia and Chemichnia.[10]	Skolithos
Glossifungites[10]	Glossifungites isp.	Campomolon, Valbona	Infilled abandoned burrows by coarse-grained skelletal debris	On the local waters during the Lower Jurassic, water motion due to the hurricane action truncated many mounds causing changes on the deposition on the sea-floor and inducing various phases of substrate infillings with carbonate mud, fine-to coarse-grained skeletal debris and fecal pellets.[10] They are assigned to Priapulida, Serpulidae, Siboglinidae, Sabellidae or even Oweniidae.
Chomatichnus[10]	Chomatichnus wegberensis	Campomolon, Valbona	Vertical burrows with preserved entrances	It is difficult to suggest this ichnogenus because on the Formation the vertical and lined burrow with a deep central crater typical of Chomatichnus is never preserved.[10] It resemble described burrows of endobenthic thalassinidean decapods, specially Callianassa subterranea of modern North Sea, Callianassa major, Callianassa californensis or Upogebia pugettensis.[10] It can be also Serpulidae Polychaetan burrows.

Dinosaurs

On the Inter-supratidal levels show that on the Rotzo Formation the Tracksites were rarely hit by Storm Waves.[25] Bella Lastra Tracksite recovers this environment, where the shales present (Where Fish & Crocodrylomorph Remains where found) are filled with plant roots, pollen grains, spores, freshwater ostracodes and the bivalve Eomiodon.[25] This was deposited mostly on a Lagoonar environment with abundant shed vegetation.[25] The main local Track record recovers specially Theropoda and Sauropoda, where the Sauropods are the most abundant tracks present (70%), moving the Otozum-like Sauropodomorphs of lower levels, with the climate changing from arid to humid.[25]

Amber[31]	Non Assignable Species	Bellori village		Amber Fragments	The Lessini Mountains Amber represents the first report of Jurassic amber from Italy and one of the very few in the world. Due to being composed by drops of less than 1 mm with preserved exceptionally intact morphologies the Bellori amber was probably neither environmentally stressed nor affected by diseases.[31] While no animal remains were found inside the Bellori Amber so far there are various traces of very small (< 1 mm) vegetal fragments, here identified as tissue remains of wood and “mummified wood”.[31] It has also a large amount of Circumpolles (Cheirolepidiaceae), and in some fragments there are traces of the freshwater algae Pseudoschizaea.[31] Although several cuticles found in Bellori could be attributed to Pagiophyllum (Araucariaceae).[31] Those lived on a coastal and wet palaeoenvironment similar to the present-day Taxodium swamps with monsoonal seasons as in the modern southern Asia.[31]

This frons genus has been Synonymized with Pachypteris , but it clearli differs due to the presence of odontopteridian pinnules, while Pachypteris has pinnules of the sphenopteridian type. Related to Arboreal Ferns.	Dichopteris visianica from the Rotzo Formation
Pseudosagenopteris[34][35][36][37]	Pseudosagenopteris angustifolia	Grey limestones of Veneto	Leaflets	Affinities with Caytoniales inside Pteridospermopsida.
Sagenopteris[34][35][38]	Sagenopteris goeppertiana Sagenopteris nilssoniana	Roverè di Velo Grey limestones of Veneto	Leaflets	Affinities with Caytoniaceae inside Caytoniales. There is a superficial doubt with the assigantion to S. goeppertiana, and du to that Roverè di Velo specimen may be confirmed by comparing them with original Zigno's Material.
Sphenozamites[34][35][36][37]	Sphenozamites rossii Sphenozamites sp.	Grey limestones of Veneto	Leaflets	Affinities with Bennettitales inside Cycadeoidopsida. Related with Cycad-like trees.
Weltrichia[34][35][36][37]	Weltrichia sp.	Grey limestones of Veneto.	Reproductive structure	Affinities with Bennettitales inside Cycadeoidopsida. Weltrichia is considered by some authors some kind of Bennetitalean Flower, putting that group on relationships with the Angiosperms.
?Pterophyllum[34][35][36][37]	Pterophyllum sp. cf. Pterophyllum platyrachis	Grey limestones of Veneto.	Leaflets	Affinities with Bennettitales inside Cycadeoidopsida. This genus has been related with the more arboreal family Williamsoniaceae, although is more probably from a low arboreal to arbustive Bennetite.
Otozamites[34][35][36][37][38]	Otozamites bunburyanus Otozamites cf. bunburyanus ? Otozamites feistmantelii Otozamites molinianus Otozamites massalongianus Otozamites sp.	Roverè di Velo Grey limestones of Veneto.	Pinnate leaf fragments	Affinities with Bennettitales inside Cycadeoidopsida. Overall, the genus Otozamites is among the most abundant flora genus recovered on some of the levels of the Rotzo Formation, and also one of the most diversified. It belongs to arbustive Bennetites.	Otozamites bunburyanus from the Rotzo Formation
Ptilophyllum[34][35][36][37][38]	Ptilophyllum grandifolium Ptilophyllum triangulare Ptilophyllum sp	Roverè di Velo Grey limestones of Veneto.	Leaves	Affinities with Bennettitales. Was previously ascribed by Guiscardi (Director of the Geology Department of the Napoles University between 1861 al 1885) to Pachypteris visianica and Cycadopteris brauniana.	Ptilophyllum grandifolium from the Rotzo Formation
Trevisania[34][35][36][37]	Trevisania furcellata	Grey limestones of Veneto	Leaves	Affinities with the genus Trichopitys, as probably a member of Ginkgoales inside Ginkgoopsida.
Desmiophyllum[34][35][38]	Desmiophyllum zeillerianum Desmiophyllum rigidum	Roverè di Velo	Incomplete leaves	Affinities with Ginkgoaceae inside Ginkgoales. Was assigned the Podozamites genus and named them Podozamites zeillerianus.
Stachyotaxus[34][35][36][37]	Stachyotaxus sp.	Grey limestones of Veneto.	Branched shoots	Affinities with Palyssia-like, a ganus that has been related to the fossil wood Phyllocladoxylon, being probably Fronds of the Podocarpaceae family.
Dactylethrophyllum[34][35][36][37][38]	Dactylethrophyllum peristictum	Roverè di Velo Grey limestones of Veneto.	Branched shoots	Affinities with Pinaceae inside Pinales. This genus resembles the modern Abies, with similar distribution of the leaves.
Elatocladus[34][35][36][37]	cf. Elatocladus sp	Grey limestones of Veneto.	Branched shoots	Affinities with Podocarpaceae inside Coniferales.
Brachyphyllum[34][35][36][37][38]	Brachyphyllum tropidimorphyrn	Roverè di Velo Grey limestones of Veneto.	Branched shoots	Affinities with Araucariaceae inside Coniferales. Brachyphyllum tropidimorphyrn shows close resemblance between African and Venetian conifers and its distribution suggests a lowland araucarian forest.[39]
Pagiophyllum[34][35][38]	Pagiophyllum rotzoanum Pagiophyllum cf. veronense Pagiophyllum valdassense	Roverè di Velo	Leaves	Affinities with Araucariaceae inside Coniferales. One of the specimens was assigned to Otozamites massalongianus, due to confusing the overlapping appearance and the Otozamites-like shape of the leaves of the apical portion of the main shoot.	Pagiophyllum rotzoanum from the Rotzo Formation
Indeterminate Specimen[34][35][38]	Indeterminate	Roverè di Velo	Nearly complete pinna	Due to the bad preservation of specimen no systematic attribution is possible.
