The denigrating chuckles long enjoyed about ancient cartographic reports of sea monsters will be stifled as this prehistoric pliosaur is added to the fossil record. At fifty-feet long, he would have brought ocean-going commerce to a standstill, assuming just a few survived into historical times. Smaller (well, thirty-feet-long) cousins, called mosasaurs, once hunted the shallow seas covering Texas. Mo, whose fossil was found in Ohion Creek in Southeast Austin, is in the dinosaur collection at the Texas Memorial Museum–one of Mr. B.’s favorite haunts.
