    Default Tuesday Trivia: New Dinosaur 🦖

    Tyrannosaurus rex was what paleobiologists call the "apex predator" of the latest Cretaceous period, a gigantic creature that stalked the Earth between 80 and 66 million years ago, eating what it pleased.

    But the T. rex didn't start out as the 42-foot-tall, 7-ton giant we know today. Its earliest relatives were human-sized, and archaeological digs in Uzbekistan unearthed a horse-sized T. rex cousin.

    Attachment 159192 T-Rex tooth, left. Timurlengia euotica tooth, right.

    Named Timurlengia euotica, it weighed about 250 kg (550 pounds) compared to Tyrannosaurus rex at about 8000 kg (17,600 pounds).

    Attachment 159193. Life reconstruction of the new tyrannosaur “Timurlengia euotica” in its environment 90 millionyears ago. It is accompanied by two flying reptiles, “Azhdarcho longicollis”. (Original painting by Todd Marshall)
