new ref, w/ corrected spelling of dino name
Just received my copy of a new paper by Clark, Perle, and Norell. It
concerns the therizinosaurid (aka segnosaur) Erlicosaurus. (And, although
they don't dwell on the subject, the name is correctly spelled with a "c",
not "Erlikosaurus", the more commonly-encountered form).
Clark, J.M., Perle A., and M.A. Norell. 1994. The skull of Erlicosaurus
andrewsi, a Late Cretaceous "Segnosaur" (Theropoda: Therizinosauroidea)
from Mongolia. American Museum Novitates 3115: 1-39.
Erlicosaurus is known only from a skull, but it is one of the
best-preserved nonavian theropod skulls known. They do not discuss
theropod phylogeny in much detail, deferring that for a later paper, but
they do conclude that the skull of Erlicosaurus shows it to be a theropod,
probably maniraptoran, and not either a very derived ornithischian- or
