Minority Media Inc released a new video for their Time Machine VR today.

In it, Dr. Hans Larsson, Research Chair in Vertebrate Paleontology at McGill University, discusses the science that went into bringing the prehistoric creatures back to life in the game.

For those curious, here is an overview from the developers:

In Time Machine VR, you are a time-travelling cadet tasked with exploring the Jurassic era and the ancient creatures that once ruled the prehistoric oceans. Use an array of advanced tech tools to track, examine, and discover scientifically accurate creatures like mosasaurs, livyatans, and megalodons. As you uncover the mysteries of the ancient past, find the connection between a prehistoric virus, the melting ice caps, and a present-day epidemic that is exterminating humankind. If you are a paleontology buff, beat the game and check out Exploration Mode, where you can revisit the oceans and unlock more intelligence about the ancient era creatures you encountered in Story Mode.

You can watch the video below. Time Machine VR is available now for HTC Vive, Oculus Rift, and PlayStation VR.
