NEXT UP: 3rd seeded Dimetrodon limbatus vs 2nd seeded Amebelodon fricki!!! #2018MMM Hand-claps for @MarcKissel who wrote this amazing BATTLE OF THE DONS!!! #2018MMM (I'm just the messenger tonight)

FIRST UP: 1st-seed Orinoco crocodile (Crocodylus intermedius) vs. 5th-seed Secretary Bird (Sagittarius serpentarius)! #2018MMM Our competitors in this first battle have so far only faced off with much smaller Arthropod foes, so the Sweet 16 Round will be their first tournament tumble with large vertebrate competitors. #2018MMM

NEXT UP: #2 seed Cape Town Chacma Baboon (Papio ursinus) vs #7 seed Porcupine (Erethizon dorsatum) #2018MMM It's round 1 all over again: Primate vs Spiky thing! #2018MMM Unlike R1, tonight's battle was a collaboration between @je_light and I!

NEXT UP: 2nd-seed Green Anaconda (Eunectes murinus) vs. 15th seed Tardigrade (Milnesium tardigradum) #2018MMM The tardigrade was discovered by German Pastor J.A.E. Goeze in 1773. He dubbed it a "water bear" based on the way it moves-like of a bear lumbering around. Water bear isn't the only name for the tardigrade, however. It is also known as the "moss piglet". #2018MMM
