(This post along with the previous two posts are based on three videos of the dinosaur world mobile adventures series on YouTube) the niobrara formation 85 million years ago, a geosternbergia watches as a squalicorax launched a platecarpus out of the water. The impact from the launch, combined with the hard landing, injured and pretty much kills the small mosasaur. The pterosaur flies down to feed on the Mosasaur while a tylosaurus attacks the squalicorax that’s about to kill the geosternbergia.
