Baryonyx walkeri was a large spinosaurid dinosaur from early Cretaceous Europe. 135-90
Baryonyx was the second largest meat eater in Europe during the Barremian period (about 127 mya), 9 metres long, 2.7 metres tall, and weighing about 1.7-2.7 tonnes (1.8-2.9 tons), although the holotype used to calculate these measurements may be a juvenile. It had a long 30 cm curved thumb claw on each hand that was probably used to process catches; this seems to be a derived feature unique to the spinosaurs in general, as a similar claw has been found on Suchomimus (another, larger spinosaur from the Barremina of North Africa) as well. Unlike its larger cousin, Spinosaurus, it walked in a bipedal fashion, although this may be due to the fact that the holotype is apparently a juvenile, or the fact that the two have seperate families errected for them. Just like other spinosaurs, it had long, crocodile-like head filled with serrationless teeth that was used to catch fish.
The Planet Dinosaur logo appears to be a Baryonyx, or at least some kind of bipedal spinosaur.
