In Depth Originally uncovered during the 1960s, the holotype teeth of Trimucrodon were originally thought to be from a small mammal. In 1973 however Richard Thulborn recognised that the teeth were actually from a small dinosaur, though his paper describing them and naming the genus did not actually get formally published until 1975. Today Trimucrodon … Read more

In Depth At the time of writing the only parts of the dinosaur Pycnonemosaurus that have been recovered include some legs and hip bones as well as caudal (tail) vertebrae and teeth. These parts however are enough to identify Pycnonemosaurus as an abelisaurid theropod dinosaur. Like with other abelisaurs, Pycnonemosaurus would be expected to have … Read more
In Depth Leptopleuron was a genus or procolophonid reptile that lived in Scotland during the Late Triassic. The exact diet of Leptopleuron is uncertain, though procolophonids in the late Triassic seem to be more herbivorous than earlier procolophonids were more insectivorous.

In Depth Named in 1856 by Joseph Leidy on the description of teeth, Palaeoscincus is today considered a highly dubious genus of ankylosaur. While over the years other fossil material has been assigned to the genus, most of this material has now been reassigned to other dinosaur genera including the dinosaurs Euoplocephalus, Paranthodon and even … Read more
In Depth The one thing that immediately stands out about Dakotaraptor at first glance is simply the large size of this dromaeosaurid dinosaur. Most dromaeosaurid dinosaurs measure in at under two meters in length, with a few genera ranging between two and three meters long. The Holotype individual of Dakotaraptor however has a reconstructed length … Read more
In Depth Although discovered in a joint Mongolian and Russian dig in 1989, Achillobator did not get named until 1999. These remains are very fragmentary but do suggest that Achillobator was a particularly large dromaeosaurid dinosaur. The achilles tendons seem to have been particularly well developed, probably to account for the extra size and weight … Read more
In Depth Descriptions of the fossils of Anguanax first came to press in 2014, though the genus was not officially named until 2015 when further fossil remains could be described for it. With the first fossils coming from Northern Italy, Anguanax is recognised as being the he first pliosaur genus to be known from articulated … Read more
In Depth Originally described as a species of Plesiosaurus by Richard Owen in 1865, it was identified as a distinct genus just under a hundred years later in 1964. Archaeonectrus is now regarded as a rhomaleosaurid pliosaur, and would have been a predator of other marine organisms. Further Reading – A monograph of the fossil … Read more
