At twenty feet long, there was little in the ocean that could consider itself safe from the jaws of the Thalattoarchon. Living in the early Triassic period it was one of the very first marine predators we know about, and remained one of the biggest hunters living in its day. Discovered as late as 2013, it provides one of the most enticing examples of the mystery of the kinds of predators that kept themselves out of sight at the bottom of the ocean.
