Summary
Spinosaurus skull reconstruction:

• Based on the 2005 Del Sasso reconstruction. Which in turn is based on specimins MSNM V4047 (998 mm snoat), IPHG 1912 VIII 19 (the front half of the lower jaw), and UCPC-2 (the crest). Rear parts of the skull based of Irritator and other spinosaurs..[1] • • The skin details are speculative but large theropods with impressions show typical dinosaurian scales.
