>>55737966i like semi-obscure dinosaurs as much as the next guy but it is absolutely meant to be spinosaurus. its godzilla posture is even similar to the way the holotype was originally reconstructed, which is also what every cheap plastic toy spinosaurus that every kid in the last 100 years played with looked like. that's what spinosaurus looks like in the public consciousness, and no surprise it's also what baxcalibur looks like.
except the face, ironically, which is comparitively long and narrow among theropod pokémon, and flared at the end, referring to modern depictions of the animal rather than the original, more basal megalosaurine reconstruction. that actually also excludes it from being based on concavenator, an animal very well known to have had a basal megalosaurine skull condition.
