Baryonyx are quick like Allosaurus and do just as much damage (but don't get a pack bonus). They don't use oxygen for swimming and can sprint in the water. Right click in the water does an AoE stun that lasts about 10 sec. Their 'C' is a... Taunt? They also jump and you can fire a weapon from their back.

Baryonyx is king of the seas! Tame with Pachyrhinosaurus kibble and use them to help you tame basilosaurus as they can stun all the Manta that follow!

Better than the megalodon in my opinion.the stun is really powerful.

The baryonyx is great for getting raw fish meat and raw prime fish meat

It's like a small Allo combined with a Kapro, in my opinion. Useful on both land & in the water. Use its secondary attack while swimming to stun, attack, and harvest. Does NOT stun Cnidarias, though, so do not expect to overpower them.
