Theropoda,
Coelurosauria

'Calamospondylus oweni' Fox, in Anon. 1866

A small theropod, Calamospondylus probably hunted the smaller animals in the Wessex Formation.They are believed to have been scansorial (could climb, but spent most of the time on the ground), although this is unlikely. They were also described as being capable of "leaping from tree to tree or...bounding from the grasp of other reptiles with an elasticity of spring equalling that of the grasshopper", which is also unlikely.

Description of Material

(Don't understand all the terminology? visit the Glossary)

There is only one known specimen of Calamospondylus, a sacrum, which consisted of five cemented, pneumatised, vertebrae with sacral ribs and portions of the other iliac bones. However, this is now lost, and nobody bothered to get a picture of it, so no work can be done on it by anybody.

Material is currently non-existant, so please report it if you find some...

How do I know if I've found a bone?
