Because I did everything from scratch, & was on a limited timeline, we were not able to fully sample Mosasauridae. But, we were able to include more spp of tylos than had ever been analyzed together before. We found three weird things:

Finally, to break the Permian streak I have the late Cretaceous aquatic Squamate group; Mosasauridae! This artwork doesn’t give the clade justice in just how diverse the group is.

While Bruce the Tylosaurus proriger is a giant, no doubt, the *true* behemoths among the Mosasauridae were to be found within Mosasaurus maximus/hoffannii, another branch of this evolutionary bush and among the last of the mosasauroids before the K-Pg extinction.
Did you know #mosasaurs can be World Record holders? Well, if you visit the Canadian Fossil Discovery Centre, you’ll meet Bruce, the 13 meter-long, #worldrecord holder for largest mosasaur on display!🥇🏆
