I was thrilled when Rob Nelson of Untamed Science contacted me about his latest video. Not only am I a huge fan of their work, this new video explains the journey behind an amazing find. According to their description:

Siats (pronounced SEE-OTTS) is a giant mega-predator (think T-Rex, but living at a different time). I just like saying that out loud — GIANT MEGA-PREDATOR! This is the first large, mega-predator found in the US in over 60 years, and it is the 2nd or 3rd largest carnivore EVER found in North America!

The production value and entertaining content that Untamed Science is known for shine through in this film. Congratulations to Dr. Lindsay Zanno of the North Carolina Museum of Natural Sciences on this amazing find, and to Rob Nelson on an awesome video!

    Well, Tyrannobdella rex (or T. rex in short) is quite a large leech with 2.7 inch but it doesn´t need much for a dinosaur to be larger…

    Sorry, couldn´t resist this bad pun
