Diagnosis
ReferenceDiagnosis
M. D. D'Emic 2013Autapomorphies of Cedarosaurus weiskopfae include: radius with well-developed flange lateral to ulnar articulation (Tidwell et al. 1999), radius with tubercle on anterior face of shaft, one-third of the way from proximal end, metatarsal II with well-developed medial and lateral tubercles at mid-shaft (pers. obs. 2010). FMNH PR 977 is referable to Cedarosaurus on the basis of two additional autapomorphies: metatarsal V only slightly expanded proximally, and metatarsal V around 1.5 times longer than metatarsal I. Also, FMNH PR 977 possesses four well-developed pedal unguals and a phalanx on metatarsal V, providing two additional autapomorphies for Cedarosaurus.
