Vellbergia bartholomaei : Tiny prehistoric lizard sheds light on reptile evolution

A group of Russian and German palaeontologists have described a previously unknown genus and species of prehistoric salamanders. The new amphibian is named Egoria malashichevi -- in honor of Yegor Malashichev a talented scientist and associate professor of the Department of Vertebrate Zoology at St Petersburg University, who passed away at the end of 2018.

NHMUK PV R 9372, Palaeosauropus sp., (a) colour photograph of the original sandstone slab and tracks, (b) 3D digital render of the plaster cast of the sandstone slab and tracks and (c) black and white photograph of the original sandstone slab and tracks. In (b), left manus and pes prints are denoted a and b respectively, the right pes prints c and e, with print d being the right manus. The indented area left of print e is identified as damage to the specimen rather than a footprint impression.

A photo of the stone men (Chimulchek Culture) in the steppe area of Altai Mountains. These figures are characteristic of the peoples who lived in the area around the time of occupation at Tongtian. These specific examples are located at the Chimulchek site (ca. 4000 years old) and not far from Tongtian Cave. Ceramic sherds from the cave suggest that the occupants in the cave shared similar cultural traits to other people in the region. Credit: Jianjun Yu

This very complete specimen of the ichthyosaur Suevoleviathan is from the Early Jurassic of Germany. Many excellently preserved ichthyosaur fossils are known from this time and have been collected from the UK and Germany. Mary Anning from Lyme Regis is intimately associated with fossil collection and found the first recognized ichthyosaur fossils in 1810. Credit: Dr Ben Moon & Dr Tom Stubbs
