Baryonx

Baryonyx is a genus of piscivorous theropod dinosaurs from early Cretaceous Europe, in what is today the United Kingdom. The holotype specimen was discovered in 1983 in Surrey, England, and was later given the name Baryonyx walkeri in 1986.

Description
In 2010, Baryonyx was estimated to have been 7.5 m (25 ft) long and to have weighed 1.2 t (1.3 short tons). It was estimated at 10 m (33 ft) in 1997, and 9.5 m (31 ft) long, 2.5 m (8.2 ft) in hip height, and 1.7 t (1.9 short tons) in weight in 1988. The fact that elements of the skull and vertebral column of the B. walkeri holotype specimen do not appear to have co-ossified (fused) suggests that the individual was not fully grown, and the mature animal may have been much larger (as attested by the size of the related Spinosaurus, which reached 15 m (49 ft) and 10 t (11 short tons). On the other hand, the specimen's fused sternum indicates that it may have been fairly mature. The second-best-preserved specimen (ML1190) was about the same size as the holotype skeleton.
