Dinosaurs from the same rocks
Plesiotylosaurus was found in the Moreno, which also holds these dinosaurs: the same region and broad span of time.
Formation data from the Paleobiology Database, counting only each genus's main formations. One formation can span hundreds of thousands to millions of years, so this doesn't mean any two of them ever met.
