Anancus

In Depth        Although not the largest of prehistoric elephants,‭ ‬Anancus stands out from the crowd with its greatly elongated tusks which could reach lengths of up to four meters,‭ ‬almost as long as the body.‭ ‬These tusks which were like in all elephants modified teeth,‭ ‬are thought to have been used to root up plants … Read more

Apatomerus

In Depth        When it comes to naming prehistoric animals,‭ ‬the names can be confusing,‭ ‬but Apatomerus,‭ ‬which means‭ ‘‬deceptive femur‭’ ‬was spot on.‭ ‬Initially thought to a thigh of a crocodile,‭ ‬Williston later declared it to be a pterosaur bone.‭ ‬Later study has now deduced that it is probably not a pterosaur bone and is … Read more

Aymberedactylus

In Depth        Aymberedactylus is a genus of tapejarid pterosaur that lived in what is now Brazil during the early Cretaceous.‭ ‬At the time of the genus description the only fossils of Aymberedactylus are the lower jaws.‭ ‬These however seem to indicate that Aymberedactylus is one of the‭ ‬most‭ ‬primitive tapejarid pterosaurs known to us. Further … Read more

Atacamatitan

In Depth        Named after the Atacama Desert,‭ ‬Atacamatitan was a genus of titanosaur sauropod that lived in what is now Chile during the late Cretaceous.‭ ‬More precise details about the genus however remain hard to establish,‭ ‬due to the fact that the remains of Atacamatitan are very incomplete. Further Reading -‭ ‬A new titanosaur sauropod … Read more

Agriotherium

In Depth        One of the better known bears in the worlds fossil record,‭ ‬the Agriotherium genus is also easily one of the largest currently known.‭ ‬With this large size it would be tempting to portray Agriotherium as a savage killers of any animal that might be unfortunate enough to be in its way,‭ ‬yet like … Read more

Apatorhamphus

In Depth        Afrotapejara is a genus of pterosaur that lived in North Africa at the time of the Early/Late Cretaceous boundary. Further Reading -‭ ‬A new‭ ?‬chaoyangopterid‭ (‬Pterosauria:‭ ‬Pterodactyloidea‭) ‬from the Cretaceous Kem Kem beds of Southern Morocco.‭ ‬-‭ ‬Cretaceous Research.‭ ‬110:‭ ‬Article‭ ‬104410.‭ ‬-‭ ‬James McPhee,‭ ‬Nizar Ibrahim,‭ ‬Alex Kao,‭ ‬David M.‭ ‬Unwin,‭ ‬Roy … Read more

Aloposaurus

In Depth        A fairly small gorgonopsid therapsid,‭ ‬Aloposaurus was represented by only a weather eroded skull until the addition of a second species in‭ ‬1953.‭ ‬This came about from a study that found another genus called Aloposauroides was actually the same as Aloposaurus. Further Reading -‭ ‬Observations on some specimens of South African Fossil Reptiles … Read more

Axestemys

In Depth        Axestemys is a genus of soft shelled turtle that lived from the Late Cretaceous to at‭ ‬least the Eocene,‭ ‬and is known from both North America and Europe.‭ ‬Instead of a hard shell,‭ ‬Axestemys would have had a tough leathery skin surrounding its body.‭ ‬Modern day soft shelled turtles can be omnivorous,‭ ‬meaning … Read more

Allkaruen

In Depth        Though only known from a few fragmentary fossils,‭ ‬Allkaruen has already proven itself to be a very interesting pterosaur genus.‭ ‬Allkaruen is regarded as being intermediate in form between the more primitive rhamphorhynchid pterosaurs,‭ ‬and the more advanced pterodactyloid pterosaurs.‭ ‬Allkaruen also shows us that only certain parts of the body would change … Read more

Asylosaurus

In Depth        The holotype remains of Asylosaurus were originally attributed to the genus Thecodontosaurus,‭ ‬but a review by Peter Galton saw these remains established as a new genus.‭ ‬The genus names means‭ ‘‬unharmed/sanctuary lizard‭’ ‬and this is a reference as to how this set of remains were shipped from England to the United States by … Read more
