This Fossil Preserves The Last Meal of a Tyrannosaur | 7 Days of Science

In the news this week there's been the reveal of a fossil preserving the stomach contents of a young Gorgosaurus, a study showing that the shocks from electric eels can transfer DNA into other organisms, the discovery of the oldest fossil mosquitos, and much more!

That little bit of Attenborough fangirling was lovely. More Emilia content, please.

[@jredmane]

The small size of the prey in the young tyrannosaur stomach contents is really cool evidence for age-based niche partitioning in the big theropods.

[@aceundead4750]

It also shows that they had good taste when it came to preferences since the stomach contents were three legs. Makes me want chicken legs

[@WillArtie]

I can't help but think about having yummy drumsticks, then accidentally falling down a mud pit, or crossing a river bed and have a flash flood take me away!

[@jredmane]

@@WillArtie yeah at least it died with a full stomach! I can't help but wonder, too, if the selective eating of what might be the "best part" of the prey indicates adult provisioning of the young? The places I've seen this kind of picky eater behavior in modern predators are where they themselves are not the ones working for the calories, such as a baby owl selectively eating only the brains of mice brought by the parent

[@FrancisFjordCupola]

That Pliosaur skull is utterly remarkable. Amazing. Hope they can excavate a whole skeleton.

[@jurgen1395]

Imagine the skull to be from the walking with dinosaurs liopurodon

[@macroglossumstellatarum5932]

And yet, the skull is still less that half the size than that of the Walking With Dinosaurs Liopleurodon. (~2m vs. ~5m)

[@daliborjovanovic510]

@@jurgen1395 One, this skull comes from Kimmeridge Clay, not the older Oxford Clay (where Liopleurodon comes from), and two, a 2-meter skull is very big but no unprecedented for Late Jurassic pliosaurs, being comparable in size to the skull of contemporary taxa like Pliosaurus funkei and Pliosaurus kevani.

[@thelaughinghyenas8465]

I have another theory about the last meal of that tyrannosaur. Daddy gave junior the leftovers of his own meals. Daddy ate the nutritious parts - the organs. Junior got what Dad could bite off as smaller pieces.

[@swhitey4310]

The organs probably never preserved being soft tissue.

[@persianking44]

The pliosaur skull and Gorgosaurus find are incredible. Almost as incredible as those puns. *Almost*

[@tolbaszy8067]

I have seen the aftermath of otters feeding on hibernating frogs they found under a frozen pond, and they preferred the hind legs to the bodies, which they just left for other scavengers on the shore. Emilia does a superb job! Thanks!

[@LilitheAmara]

Emilia has been awesome! She is a perfect fit with the vibe of the channel. It's cool that this channel has collected all of these fun people to talk about science in an engaging way. Definitely would love to see more Emilia videos! 😊

[@johnf3f810]

Just my 2p, but your presentation is getting better every video. Though you did have some spetacular finds to report on this week!

[@matthewmarx9251]

I think the reason why the young Gorgosaurus ate only the hind limbs of the Citipes is partly because it was smart enough to know that those were the meatiest as well as the most nutritional parts of the animal and partly because there were so many of the little buggers that it could afford to be wasteful. I find this behavior more comparable to orcas that would only feed on the tongues and lips of whales as well as the liver of sharks since not only were they high in nutritional value, but also because with so much prey around they can afford to be wasteful. This is not what we would expect from a carnivorous reptile that would normally eat every part of an animal and not know or even care which part is the most nutricious.

[@edgeeffect]

I love the anomalocaris clinging on to the fairy lights. ... and I've now got images of a bunch of young Tyrannosaurs hanging around the fried chicken shop of a Saturday night.

[@MrHavadollar]

Great job, Emilia. Glad to see you're adding your own flair. It is funny that you're talking about chicken legs and chickens are indeed descended from therapod dinosaurs and are closer than many of other avian dinosaurs to the therapods. So what does T-Rex taste like? I'm sure T-Rex would probably get the first taste of us if they were around for any tasting.

Good job, Lady of Science Of course, Saber tooth cats are always of interest. Thanks for informing me

[@fluoxeturtle]

The Drumsticks bit got me thinking. If birds are dinosaurs, does it technically mean all dino meat is essentially poultry? Well, fowl, technically, but You know what I mean. I don’t need sleep I need answers.

[@fermintenava5911]

No, it means that poultry and fowl are dino meat, as all birds are dinosaurs, but not all dinosaurs are avian 😉

[@fluoxeturtle]

@@fermintenava5911 u damn right but I’m just so fixated on the fact that velociraptor meat could’ve been tasting like really game-forward duck with a texture of a real lean turkey…. Damn dinos would’ve been tasty and fun to cook with, I feel extra sad about it right now

[@fluoxeturtle]

And the idea that T.Rex being a chonky predator with big mass and big need to store oxygen would probably have taste like fun and weird twist on a bear meat and the poultry? Or like a juicy venison, with those big boy muscles? Ohhh to cook that bad boy’s tail cut with some good wine and balsamic vinegar marinade? Not to mention it would feed a small village for a day or two, this would be GOOD

[@jimparsons6803]

Interesting and thanks. Liked the bit about the electric eel? About the transference, apparently, caused by the eels' discharges. DNA experimenters, if memory serves, started doing that in the mid 70s with small transformers. Boggle. Electrical flow, maybe not quite to the same voltages, also occur when fresh water enter the present day oceans. More boggle. Maybe that last might acount for some of the diversity of life forms in the tropics?

Eating the young that the none exsistant mid size dinosaurs would have if not for baby red,is fascinating

[@totobeni]

just because only the back part of the eaten dino was pressent in the stomach don't mean he only ate them parts, the more probable reason would be that he shared his meal with sibings and thoes parts is what he got.

[@newton9837]

it seems to me that if the this year is the first time the IUCN did a freshwater fish survey, and this year they found that there are 2000 more endangered species, doesn't make sense that at least some of those 2000 came from freshwater fish that had not been previously surveyed? It could be there was a reduction in the number total of endangered species but the survey put 3000 previously uncounted species on to the list.

[@Duron0]

There is something utterly amusing about imagining a juvenile/adolescent gorgosaurus as a picky eater, only eating their favourite part of the meal. Although, perhaps the animal did not choose to finish the meal early - maybe it was scared off by another predator mid-meal, like an older gorgosaurus? It's a very common occurrence in the wild today, so how different was the Cretaceous?
