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 currently known from only a lower jaw Aetodactylus is believed to represent an ornithocheirid pterosaur, and as such it is only the second of its type to have been discovered in North America. The pointed teeth of Aetodactylus are pointed and evenly arranged into pairs, the first of which project forwards. This … Read more
