K Carpenter - Carnivorous Dinosaurs, 2005 - doc.rero.ch
The small tetanuran-basal maniraptoran theropods Ornitholestes hermanni and Coelurus
fragilis have been described only briefly. Owing to their importance to evolutionary studies of
theropods, a detailed description is presented here. Ornitholestes has a relatively short neck
and body (as indicated by the anteroposteriorly short cervical and dorsal centra); cervicals
with opisthocoelous centra; prezygapophyses of distal caudals extending about midway on
the preceding caudal; ventrally bifurcated chevrons on distal caudals; a long, low ilium; a …
