In Depth        Out of all the hadrosaurs†(‬also known as the duck-billed dinosaursâ€) ‬Parasaurolophus is one of the most†‬widely recognised thanks†‬to its very distinctive skull crest.†‬ The name Parasaurolophus is a bit of a mouthful,†‬but this is based around the early interpretation that Parasaurolophus was similar to another genus names Saurolophus†… Read more
In Depth        Tremataspis was a jawless fish known to have lived in the European ocean waters of Silurian period.†‬The genus is noted for having a more rounded bony head shield than that seen in other genera,†‬which may have helped Tremataspis to push through softer bottom sediment on the ocean floor.

In Depth        Nundasuchus is a genus of archosaurian predator that lived in Tanzania during the mid Triassic.†‬Nundasuchus superficially resembles a rauisuchian,†‬however the exact phylogenetic position of Nundasuchus is still uncertain at the time of writing.†‬Currently most prefer to consider it a member of the Pseudosuchia,†‬the same group that also includes the … Read more
In Depth        Unfortunately Saurosuchus is only known from incomplete remains,†‬but those that are known indicate that it was big.†‬Key to identifying the fossils as being those of a predator is the skull that has several classic predatory characteristics.†‬One is the fact that the skull is wider at the back than†‬at†‬the … Read more
In Depth        Though only small,†‬Echinochimaera is still a very interesting fish that is known to have swum in the waters of what is now Montana during the Carboniferous.†‬Echinochimaera had a deep round body that was propelled by a relatively thin tail which ended in a small caudal fin.†‬This indicates that Echinochimaera was … Read more

In Depth        Eobrontosaurus was initially described as a new species of Apatosaurus called A.†‬yahnahpin by James Filla and Patrick Redman in†‬1994.†‬However when the material was re-examined by Robert Bakker in†‬1998†‬he found that it represented a similar but more primitive sauropod dinosaur to Apatosaurus.†‬The second species of Apatosaurus,†‬A.†‬excelsus,†… Read more
In Depth        Ctenosauriscus is the type specimen of the Ctenosauriscidae,†‬a group of sail†‬backed rauisuchian archosaurs that also include others such as Arizonasaurus.†‬Ctenosauriscidae however is†‬only known from post cranial remains that reveal it had a large sail on its back.†‬Like in related reptiles,†‬this sail was supported by the enlarged neural … Read more
In Depth        Llanocetus is by far one of the most primitive baleen whales so far discovered,†‬so primitive it was that Llanocetus didn’t actually have†‬baleen.†‬Granted this sounds like a paradox,†‬but Llanocetus has been identified as a baleen whale upon the basis of the shape and form the skull.†‬But the teeth to … Read more
