Dental anatomy of the apex predator Sinraptor dongi (Theropoda: Allosauroidea) from the Late Jurassic of China

Abstract: The dental morphology of the holotype of the theropod Sinraptor dongi from the Jurassic Shishugou Formation of China is comprehensively described. We highlight a combination of dental features that appear to be restricted to Sinraptor: (i) crowns with denticulated mesial and distal carinae extending from the root and an irregular surface texture on the enamel; (ii) a D-to salinon-shaped cross-sectional outline at the crown base in mesialmost teeth; (iii) mesial crowns with mesial carinae spiraling mesiolingual… Show more

“…In the first search we followed Hendrickx et al . (2020), with the combination of TBR (branch swapping with random seed = 0 and 5000 replicates, and 10 trees saved per replica) and the TNT algorithms Sectorial Searches, Ratchet (perturbation phase stopped after 20 substitutions), and Tree‐fusing (five rounds), until 100 hits of the same MLT were achieved. We conducted a final round with the MLTs obtained with TBR branch swapping, with the command ‘xmult = hits 100 rss fuse 5 ratchet 20’ followed by the ‘bb’ command.…”
