A trio of three juvenile Diplocaulus in a burrow of eight (plus one juvenile Eryops) were found to have been partially eaten by the sail-backed synapsid Dimetrodon, which likely unearthed the amphibians during a drought. One of the three was killed with a bite to the head, taking part of its skull and portions of the brain, a fatal injury that ...
This list of prehistoric amphibians is an attempt to create a comprehensive listing of all genera from the fossil record that have ever been considered to be ...
Size estimation of Beelzebufo. In early studies, it is suggested that Beelzebufo had snout-vent lengths of up to 42.5 cm (16.7 in). [1] But in later studies, animals of this species estimated to have grown to at least 23.2 cm (9.1 in) (snout-vent length), which is around the size a modern African bullfrog can reach. [5]
Vertebrate fossils found at these Wolfcampian sites consist of fish, amphibians, and reptiles, including charismatic pelycosaur reptiles such as Edaphosaurus. The presence of large ectotherms , assuming that these extant reptiles are similar to modern day species, hints at a daytime temperature range between 25-41 °C, and not dropping below 5 ...
Swallowing was done by tipping the head back, as seen in many modern amphibians and in crocodiles. Evolution of a deeper skull, better jaw control and a reduction of the palatine tusks is only seen in the more advanced reptile-like forms, possibly in connection with the evolution of more effective breathing, allowing for a more refined hunting ...
Paleontologists with the Smithsonian National Museum of Natural History have discovered a previously unknown prehistoric species — a 270 million-year-old amphibian with wide eyes and a ...
Temnospondyli (from Greek τέμνειν, temnein 'to cut' and σπόνδυλος, spondylos 'vertebra') or temnospondyls is a diverse ancient order of small to giant tetrapods—often considered primitive amphibians—that flourished worldwide during the Carboniferous, Permian and Triassic periods, with fossils being found on every continent.
About 280 million years ago, a large creature built somewhat like a salamander but with frightful fangs prowled the swamps and lakes of what is now Namibia, ambushing prey as a top predator in a ...
