Nessov only had the _smaller_ segnosaurs (known only from fragmentary
material from the Lower Cretaceous and, perhaps, footprints from the Late
Jutrassic; none named) up in the trees eating wasp's nests. The larger forms
(which are known from better material, and include _Alxasaurus_,
_Segnosaurus_, _Erlikosaurus_, _Enigmosaurus_, _Nanshiungosaurus_, and
_Therizinosaurus_), he said, were terrestrial rather than arboreal--like
megatheres vis a vis tree sloths.
