Managed to get my old scanner working, here is a higher quality image of Hesperornithoides. This small Late Jurassic #theropod, about a metre long, is the earliest definitive troodontid. I have depicted it catching a mouse-sized mammal, Glirodon. #palaeoart #dinosaur

Repost of the giant, underrated #theropod Yangchuanosaurus shangyouensis. The well known subadult holotype is ~ 7.5 m, about the size of Allosaurus, but the fragmentary adult specimen - depicted here - is about as big as Jurassic theropods got, over 10 m long. #palaeoart
