As much as I love Dr Grant, I think as far as Jurassic Park goes im more excited to see the kids explore more of Nublar in the 2nd season of a cartoon than whatever they came up with to follow that stupid FK ending.
Appears to be a Jurassic-fied Lystrosaurus, a animal that is not a dinosaur and predates them. Other confirmed JW3 animatronics are the baby Nasutoceratops and Compys:
