Vendotaenid

Vendotaenids are ribbon-shaped, carbonaceous, Precambrian macrofossils.[2] They are thought to represent giant sulfide-reducing bacteria, similar to Thiomargarita.[2] Many form genera, including Vendotaenida, have been described.[3]

Vendotaenid
Temporal range: 650–530 Ma
Scientific classification
Genera[1]
  • †Kroloataenia
  • †Tyrasotaenia
  • †Vendotaenia

Morphology

The fossils reach around 15 cm in length and are around a millimetre in width.[2]

Affinity

Originally interpreted as brown algae, the fossils are now thought to represent sulfide-reducing bacteria.[2]

Occurrence

The carbonaceous fossils, which can be extracted by HF dissolution, are found in precambrian to Early Cambrian rocks, dating from approx. 650 to 530 million years ago.[2]
