(image source: https://www.pinterest.com/pin/706009679067998263/) Host Matthew Donald and guest co-host Lawrence Mack discuss Shastasaurus, the biggest marine reptile and biggest non-whale animal of all time; jeez, who are you trying to impress? From the Late Triassic, this 70-foot ichthyosaur goes back and forth in being classified as either its own genus or a subspecies of Shonisaurus, but for now it's its own genus, until paleontologists get drunk and write a paper changing it again.
