Shonisaurus, marine giant! Found in 1920 in Nevada’s Late #Triassic ~235 mya Luning Formation, this absolutely gigantic marine reptile is not a dinosaur, despite the saurus name, but is rather a huge #ichthyosaur! At nearly 50’ in length it is astounding to behold here at the Nevada State Museum in Las Vegas, Nevada. Longer, and probably heavier, than a full-sized yellow school bus, I grew up thinking it lived in schools as 37 skeletons were excavated from one Nevada desert locality in the 1950s
