Palmarius excellens

Palmarius excellens, the "perfect masterpiece," or so Dr. Wu would have it known. This creature is the result of extensive testing with the DNA of numerous theropod dinosaurs. Spinosaurus, Tyrannosaurus, Deinocheirus, Therizinosaurus, among others, with cassowary DNA to fill in the gaps (which seems to have given it its striking colors.) However, whether it be from its troubled origins, or its inadequate habitation, Palmarius shows maladaptive quirks...

The worries started when the specimen, perhaps stressed from its cohabitation, killed and attempted to eat its siblings in the nest, with employee interference having been necessary to keep it from choking to death. Even now, at its full size of 49 feet long and 15 tons, small disturbances, such as birds or zookeepers, elicit wild threat displays from Palmarius, hissing loudly and flashing its eyespots aggressively. Some are concerned it won't be long until the specimen snaps altogether...
