In Depth The Cedar Mountain Formation of Utah is well known for the large number of armoured dinosaur genera known to have lived in what would become Utah back in the early Cretaceous. Peloroplites however stands out from other genera however because the ulna (one of lower fore leg bones) was quite long and straight … Read more

In Depth Although only named from partial skull remains representing what seems to be a small dinosaur, Ajkaceratops has been one of the most important dinosaur discoveries of the early twenty-first century; it is the first ceratopsian dinosaur definitively proven to have come from Europe. Ceratopsian dinosaurs were very common across Asia and North America … Read more
In Depth At just over half a meter in length, Shuvuuia is not just one of the smallest alvarezsaurs, it is among the smallest known dinosaurs. It is thanks to this small size that the Shuvuuia holotype was so well preserved because it could be buried much more quickly than a larger dinosaur (larger dinosaurs … Read more
In Depth Coelophysis is frequently used as an example of the early dinosaurs. Its bipedal stance from two legs that supported its body from underneath as opposed to sticking out to the sides, smaller arms and head mounted on an ‘S curved’ neck give it the distinctive theropod look. Coelophysis also had sharp recurved teeth … Read more
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 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
