Pliensbachian life

Ohmdenia is an extinct genus of prehistoric bony fish that lived from the Toarcian stage of the Early Jurassic period. Ohmdenia was first described in 1953 by Bernhard Hauff, based on a fossil found in the well-known Posidonia Shale in Holzmaden, Germany. For a long time this animal has been considered a close relative of Birgeria, a great predator typical of the Triassic period with an uncertain systematic position. Further studies have shown similarities with the Pachycormiformes, a group considered close to the origin of teleosts and also including giant forms and planktivores (e.g., Leedsi

Bocatherium is an extinct genus of tritylodont mammaliamorphs from the Pliensbachian (Early Jurassic) of Tamaulipas, Mexico. It is known only from a skull found at the Huizachal Canyon locality, "a Pliensbachian floodplain siltstone in the La Boca Formation".

Prodactylioceras is genus of ammonite that lived during the Pliensbachian stage of early Jurassic. It has evolved from Reynesocoeloceras, but maybe not directly, but through Bettoniceras. Its fossils were found in Europe, Asia and North America.

Uptonia is an extinct ammonite from the Lower Jurassic that's included in the eoderoceratoidean family Polymorphitidae.
