Prized for their caviar and flavor, not many foodies may appreciate that the sturgeon on their plate is actually a living fossil, existing since the days of the Upper Cretaceous. And its progenitors entered the scene as early as the end of the Triassic. Scientists and skeptics have even hypothesized that the Loch Ness Monster might in fact be a giant sturgeon. It makes sense since there’s been sightings of the fish measuring as much as 20 feet in length!
