In dinosaur news this week: Tone Blakesley's new paper describing a Middle Jurassic lagoon preserved in modern day Scotland; The documentary of the tracks that Tone made to accompany the paper We also talk to Tone Blakesley, a Master's graduate University of Edinburgh and lead author of a new paper about 131 dinosaur footprints on the Isle of Skye in Scotland. This week's dinosaur of the day is Ornithodesmus Dromaeosaurid that lived in the Early Cretaceous in what is now the Isle of Wight, England Looked like other raptors. Walked on two legs, covered in feathers, had a small head and long tail Estimated to be almost 6 ft (about 1.8 m) long Probably had sickle claws on its second toes Probably carnivorous Originally thought to be a bird based on its hip bones (sacrum), then later considered to be a pterosaur Eventually, more of the pterosaur bones were found, and a study found Ornithodesmus to be a small theropod Type and only species is Ornithodesmus cluniculus Described in 1887 by Harry Seeley, based on six fused vertebrae from the hip (the sacrum), that William Fox found Seeley thought the fossils were from an early bird Genus name means "bird link" Species name means "little buttock" and refers to its small thighs Later in 1887, John Hulke, in an anonymous paper, suggested the fossils were from a pterosaur instead. Seeley later agreed when he described the skeleton of a pterosaur he thought was a close relative to Ornithodesmus. Seeley named it Ornithodesmus latidens Seeley considered the sacrum of both species to be similar For more than 100 years, the skeleton of Ornithodesmus latidens was what people thought of for Ornithodesmus, and not the fragmentary skeleton of Ornithodesmus cluniculus … read more at https://iknowdino.com/Ornithodesmus-E...
