The latter are firmly linked to other tetanurans.<br />I do not think that the beak cited by Sereno is homologous to that in Limusaurus. The condition in Kryptops probably derived from bone roughness on the skull: Limusaurus lacks these structures. Its beak is probably similar (by convergence) to thatAndrea Cauhttps://www.blogger.com/profile/10855060597677361866noreply@blogger.comtag:blogger.com,1999:blog-2156944512466583246.post-13473591107835855712009-06-18T22:12:35.024+02:002009-06-18T22:12:35.024+02:00Really interesting, I had read somewhere that the ...Really interesting, I had read somewhere that the spinosaurs were now related to the ceratosaurs, but I can't remember where... Could Elaphrosaurus be an early spinosaur?<br /><br />Could this beak on Limusaurus possibly explain the possible beak Paul Serano has mentioned on Kryptops? A primative condition?<br /><br />Anyways really cool beastie and a great post, looking forward to the next Bretthttps://www.blogger.com/profile/12168403050889835504noreply@blogger.comtag:blogger.com,1999:blog-2156944512466583246.post-16200953101536053582009-06-18T21:25:22.464+02:002009-06-18T21:25:22.464+02:00- Ozraptor è basato su un singolo frammento distal...- Ozraptor è basato su un singolo frammento distale di tibia.
