Cretaceous seas were inhabited by several Mosasaurus species, not all of them giants.
This is one of the medium-sized Mosasaurus, M. missouriensis, an exceptional specimen found in Alberta. Lizardfish bones were in its gut contents. The prey had been bitten into swallowable chunks. 🧪

RFK Jr. and Mike Tyson want you to believe that MAHA is just about eating healthier.
But in reality, MAHA has been focused on firing the food and medical research experts who actually make America healthy.

White House and DHS cancelling a $11b payment in disaster-relief funds meant to reimburse states that have already had to bear the brunt of recovery — from NC to TX.
It becomes an IOU for next year, reducing FEMA's already diminished $26.5b by nearly half. We'll have only $15.5b until Sept. 2026.
