From the United States, we have a new entry in the "top prehistoric predator" competition. While I still give that title to T. rex for land predators and Dunkleosteus terrelli for marine predators, Siats meekerorum (the genus name is from a legendary Native American monster) was over 9m long, with three-clawed hands and a generally fierce demeanor, especially in the artist's concept attached to the linked story. To an amateur, the head and claws give this 100-million-year-old beast a more allosaurid look than a tyrannosaurid one, but that's just on looks: the article doesn't offer much on the actual relationships.
It's not only an awesome critter but a good reminder that the dinosaur record is far from being filled in. Who knows what's next?
