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.

Baryonyx in The Land Before Time

Baryonyxes
A quartet of Baryonyx appear in The Land Before Time XIII: The Wisdom of Friends, serving as the main antagonists.

They are first seen not long after the Prehistoric Pals bring Loofah, Doofah, and Foobie into the Mysterious Beyond in search of Berry Valley, antagonizing the three Yellow Bellies before being defeated and buried in a pile of stones, from which they soon escape.

They later appear at the film's climax, and are presumably killed when they are cornered off the edge of a crumbling cliff by the Yellow Belly herd.

They, along with Spinosaurus, the sail-backed spinosaurid, they the only spinosaurids to be represented in the film series.
