Document Summary

1. 3: identify the two major types of pelves in dinosaurs. Skeletal differe(cid:374)(cid:272)es a(cid:374)d si(cid:373)ilarities are used to sort di(cid:374)o(cid:859)s i(cid:374)to groups. **remember that birds are not a part of this category because they are(cid:374)(cid:859)t (cid:272)lassified as (cid:271)ird-hipped. Instead, they are a part of a special group of sauris(cid:272)hia(cid:374) di(cid:374)o(cid:859)s, the(cid:455) (cid:272)ha(cid:374)ged their pu(cid:271)is fro(cid:373) e(cid:454)te(cid:374)di(cid:374)g forward to extending backwards** Potential complication: s a(cid:374)d o(cid:859)s share a (cid:272)o(cid:373)(cid:373)o(cid:374) a(cid:374)(cid:272)estor (cid:449)ith ea(cid:272)h other and paleontologists are not sure what this ancestor was like. Both of these groups are based on the pubis shape of the shared ancestor. 1. 4: identify the major bony features of general dino groups. Saurischians are herbivores and there are 2 major groups of these di(cid:374)o(cid:859)s: sauropomorphs = large herbivores with long necks. Prosauropod: an early group of sauropodomorphs and were the first group of large-(cid:271)odied her(cid:271)i(cid:448)orous di(cid:374)o(cid:859)s to e(cid:448)ol(cid:448)e.
