Calamosaurus

Calamosaurus was a genus of small theropod dinosaur from the Lower Cretaceous  of the Isle of Wight.

 Paleobiology 
As a possible basal coelurosaur, Calamosaurus would have been a small, agile, bipedal carnivore.  Naish et al 2001. estimate the living animal would have been around 3–5 meters long (9.8-16.4 feet), with a small head given the build of the neck vertebrae.Naish D; Hutt S. and Martill D.M. 2001. Saurischian dinosaurs 2: theropods. In: Martill D.M., and Naish D. (eds) Dinosaurs of the Isle of Wight. London The Palaeontological Association, 242-309. 

There is too little material to say much more about it.
