Tyrannosaurus Did Not Have Lips!!! Part 2 of our Tracy Lee Ford Conversation

No lips for you! Tracy Ford explains why theropod dinosaurs like Tyrannosaurus rex did not have lips and comments on the "lippy" paper. ***Note to watchers: I have been meaning to upload this video since February 15th, 2023. However, things kept interfering (check out our socials to see why :-)). It was on my upload schedule for early April, but then today happened. By today I mean the "Lippy" paper dropped! Cullen et al. 2023 argue that theropods had lips. Tracy reached out and asked if he could record his comments on the new paper, which you can hear at Minute 19. I promised him I'd upload it tonight, so here it is, minutes before midnight EST!*** **Note to watchers 2: Sincere apologies for the blurry camera work in places! I will improve my impromptu run-and-gun filming (I'm a wildlife shooter by preference, you'd think I would have nailed this! SMH)** You may recall the video Fossil Crates shot last year when we ran into paleontologist Tracy Lee Ford at the Tucson Gem and Mineral Show.  He gave us an impromptu "why theropods do not have lips" conversation while we gathered around the incredible Triebold Paleontology Inc.'s Tufts-Love Tyrannosaurus rex skull. All of us had a lot of fun hearing Tracy's nuanced take on why no lips. You can watch it here:    • World's Best Tyrannosaurus Skull shares se...   Well, we are back! Again, we met in Tucson at the Tucson Gem and Mineral Show at the amazing Triebold Paleontology Inc.'s Tufts-Love Tyrannosaurus rex skull. This time Tracy had props! He walked us through his "no lips" argument and made some striking points.  Will this be the next great "It's an aquatic pursuit predator" "No, it's not, it's a shore assassin"? Perhaps "Nanotyrannus vs. No-no-tyrannus"?    We've got our popcorn out here at Fossil Crates and are excited that a peer-reviewed lip paper hit the market! Let's see what the no-lips camp does in the literature.   These kinds of debates advance science forward while providing plenty of passionate supporters on either side. As a sauropod lad with no dog in this fight, I prefer my popcorn with extra cinnamon and sugar, please!
