In Depth Daemonosaurus has a distinguished skull that is unlike any other dinosaur currently known from the time. The upper teeth are mounted in a short snout and protrude forwards from the tip. This is mirrored in the lower jaw and was the inspiration for the type species name D. chauliodus that loosely translated means … Read more
In Depth Dahalokely is so far only known by very incomplete remains, but if it’s identification as an abelisauroid is correct, then it certainly was very small for its type. Alternatively, if Dahalokely turns out to be a noasaur, a group of theropods closely related to abelisaurs, then it would be expected to have a … Read more
In Depth Dyslocosaurus is a genus of diplodocid sauropod dinosaur that lived in North America during the late Jurassic. It is unknown exactly where the type fossils of Dyslocosaurus are known from as when they were first discovered they only had ‘Lance Creek’ written on them. There is a Lance Formation that is named after … Read more
In Depth Lagerpeton is a very primitive dinosauromorph that lived in South America during the early Triassic. So primitive is Lagerpeton that it is easily among the most basal dinosauromorphs that we currently know about. Several features can be observed in the known Lagerpeton material including neural spins on the dorsal vertebrae that are slanting … Read more
In Depth Cathayopterus is another member of the filter feeding group of pterosaurs that are known from all over the world with particularly notable genera hailing from South America (Pterodaustro) and Europe (Ctenochasma).

In Depth Dactylosaurus was one of the smallest known pachypleurosaurs, a group of marine reptiles with close associations to the nothosaurs, though opinions differ on if they should belong within the Nothosauroidea or be separate to them. Dactylosaurus may have been fed upon by other marine reptiles and large fish such as primitive sharks like … Read more

In Depth Based upon the description of a partial skull, the validity of the Stormbergia genus has been questioned as some have proposed that the skull may represent the fully grown adult form of Lesothosaurus. If this is correct then Stormbergia would actually be a synonym to Lesothosaurus. Further Reading - The ‘fabrosaurid’ ornithischian dinosaurs … Read more

In Depth Chenanisaurus is a genus of abelisaurid dinosaur that lived in North Africa towards the end of the Cretaceous period. Chenanisaurus is named from the description of a partial lower jaw, and while this does not give us much to go on, it does reveal a few things. While the jaw is incomplete, it … Read more
