[@mikewilson858]

Right. A huge chunk of their diversity is lost to us. You will see the same fossil beds mentioned over and over again. Our picture of the Mesozoic comes from a hand full of peepholes at particular times and places. And then there are environments unlikely to produce fossils at all that come times have the most odd creatures. The deep sea and small volcanic islands tend to get recycled into the crust.

[@moukidelmar]

I live in SW Virginia and we don't see a lot of dinosaur fossils in Appalachia because the Appalachian mountains absolutely dominated the subcontinent throughout the mesozoic. People don't realuze that the Appalachian mountains today are just the barest weathered ankles of what they used to be, the Appalachian mountains used to be larger than the Alps and throughout the Mesozoic they were in their errosion phase, which is why dinosaur finds in the east are almost exclusively found at the coasts or in river mouths like in New Jersey, Alabana or the Chesapeake Bay. Around here, we find a lot of fossils from the archeozoic and paleozoic, like sea creatures, coal and limestone, because the Appalachian mountains used to be sea floor, and lots of fossils from the cenozoic (stuff that hasn't been gone that long like mastodon teeth)

[@peterschorn1]

"...the Newark Supergroup..." I'm imagining a Family Guy-style hard cut to a bunch of dinosaurs in a huge arena, singing ABBA in New Jersey accents.

[@beedrillbot121]

I would like to add a few things that I personally have learned when doing my research on Appalachian Biodiversity. For one the Newark Supergroup, while not containing a massive number of animals, has preserved several Aetosaurs, Psuedosuchians, and a few Archosauromorphs such as Rutiodon, Hypuronector (a weird little drepanosaur with a leaf shaped tail), Doswellia, Lucasuchus, Carnufex, and a unique species of Postosuchus (P. alisonae). Additionally in the Portland formation, there have been very few but interesting fossils that did preseve. Such as Podokesaurus, which was lost in a fire in 1917, Anchisaurus, which we have more than a handful of fossils from, as well as two interesting recent finds. One being the distal end of a humerous from a Theropod, which is more similar to the ones found in Crylophosaurus, than Dilophosaurus, as well as being much larger and denser than both of theirs. As well as the wrist bone of a Non-pterodactyloid Pterosaur, which is uniquely dense for a pterosaur wrist, potentially meaning it could be a forest dwelling pterosaur opposed to the more typical oceanic pterosaurs we know. Meanwhile the Late Cretaceous fossil beds are very interesting. As deinosuchus appears to be present throughout most of them, whereas the two know Appalachian large carnivores from the late cretaceous are rather small, with one Appalachisaurus fossil having Deinosuchus bite marks on it. Potentially pointing to Deinosuchus being the dominant predator of costal Appalachia during the Cenomanian. However because we are lacking a massive amount of Western Appalachian fossils with only a tantalizing amount from bloat and float specimens. We have no clue what lived in the western plains of Appalachia aside from a few scarce Hadrosaur and Nodosaur fossils. Speaking of Hadrosauroids, Appalachian Hadrosaurs appear to be split into three distinct groups. Small bodied Hadrosaurs such as Claosaurus which were 6 meters long or shorter. Medium sized Hadrosaurs such as Hadrosaurus which were anywhere from 6-10 meters long. And Edmontosaurus sized Hadrosauroids with the current only known examples of Parrosaurus and Hypsibema, which could be anywhere from (12-19) meters long. These massive Appalachian Hadrosauroids also have had a difficult problem in their placement on the hadrosaur family tree, potentially pointing to them forming their own distinct group of Appalachian Hadrosauroids. This refugia appears to have come to an end some time during the Maastrictian, as begining in Maastrictian age rocks, we have found distinctly Laramidian fauna. Such as a Ceratopsian tooth crown being found in Missouri. Or there being quite a few lambeosaur and saurolophine fossils being discovered in New Jersey. While the Hadrosauroid fossils at the same time appear to have become rarer. Though that might be because it is a costal enviroment with its own bias. Additionally an extremely fragmentary Lambeosaur, Hadrosaurid, and Tyrannosaur fossils was discovered in Maastrictian age rock from Nunavut Canada, showing just a glimpse into Arctic Appalachian fauna, though it is even more fragmentary than most Appalachian dig sites, which is saying a lot. I felt like adding this merely because I have become extremely interested in Appalachian fauna, especially since it so rarely gets covered at all. Despite us having at least two decent bone beds in Missouri and North Carolina. Them being the Tar Heel/ Coachmen Formation of North Carolina which has a wealth of fossils preserved with at least three Hadrosaurs, a Leptoceratopsid jaw, two Tyrannosauroids (Appalachiasaurus and a Dryptosauroid), two dromeosaurs (Saurornitholestes and a Deinonychus sized Dromeosaur), and some Nodosaur and Deinosuchus remains, and a still unamed Missouri bone bed that has preserved a Parrosaurus nesting ground, along with some fragmentary Tyrannosaur, Dromeosaur, and Ornithomimid remains. Sure Appalachian fauna are generally terribly preserved on account of most being sea deposits. But I think this video is a great way for people to start learning about Appalachian fauna. I just wanted to add some of what I know about them from just learning about them in my own time.

[@bencoomer2000]

[@ronb8066]

Very valuable and interesting comment, thank you. You are probably aware of the work of researchers Brownstein and McLean on the Cretaceous dinosaurs of Appalachia. With respect to Laramidian fauna in Appalachia during the last stage of the Cretaceous (the Maastrichtian): yes, the Western Interior Seaway closed from about 69-70 my ago, forming land-bridges that would have allowed an invasive migration of species, and indeed, as you point out, western taxa seem to have invaded Appalachia during the last 3 my or so of the Cretaceous.

[@DrBunnyMedicinal]

Wonderful and informative comment, many thanks! 👍

[@ATMLVE]

Thanks for the great comment! I'm gonna look more into some of the things you mentioned

[@andyjay729]

Is it also possible that the early Appalachian Mountains also played a role in isolating dinosaurs to the east of them before the Interior Seaway opened? Remember, they were once the size of the Himalayas.

[@patreekotime4578]

Right, and the Appalacians themselves would have been both a poor environment to live on, and a poor preservation environment.

[@blankspace998]

Exactly my thought too! The Appalachians are ancient and used to be way taller. And expect seeing dinosaurs there is like expecting seeing rhinos and elephants in the Himalayas

[@Lord.Kiltridge]

When I was a youth, paleontologists were in the habit of speaking in absolutes. They would say things like "Dinosaurs were slow and cold blooded" and "Not related to birds." This language seriously undermined their credibility. I'm glad this has been recognized and the language replaced with more flexible choices.

[@Popcornchicken42]

​@@Popcornchicken42credibility to people who think like mathematicians, chemists, physicists or statistitians. Whoever is used to having either absolute proof or having to demonstrate things with repeatable experiments will doubt the certainty on the words for a field that can never get either alone. Hence why the language changed over time to convey to students that historical fields work on hypothesis through available information and you have to always remember your samples are biased by preservation factor you don't know from the start. A statistician is expected to talk in possibilities because we have data without having the mechanics or being able to replicate the underlying conditions. So are now the expectations over history and paleontology =)

[@ErgoCogita]

To be fair, most dinosaurs were not directly related to birds. Further, “undermining credibility” is a rather post hoc charge considering the lack of data for them to arrive at closer approximations to truth. We have discovered and learned more about their relationships and biology in the last 30-40 years than in all the time since they were first being described in science journals 200 years ago. Data collection and synthesis takes time. Then, dissemination takes even more time.

[@alexhaladay4345]

I got to imagine too, we simply weren't looking for them before we built our cities on the east coast. A lot of major cities on the east coast were established before we the 1st dino bones were discovered unlike the west coast. Who knows how many are under Philly or Boston that people may have seen and just threw out not knowing what they were

[@andyjay729]

On top of that, when the Atlantic Ocean opened almost right under the future sites of those cities, how many early dino fossils did that obliterate? The very hard igneous traprock formations throughout the NYC area (including those big rocks throughout Central Park and the New Jersey Palisades) and New England are testament to the geological violence of that event.

Appalachia also seems to have been comparatively stable. Laramidia still had the Rocky Mountains piling up, constantly slightly changing the available biomes, or causing minor regional extinctions through volcanic eruptions or changes in rain/winds/rivers, which gave it a constantly shifting set of niches the animals there had to compete for. But over on Appalachia the biggest change was the initial increase in rain thanks to the Western Interior Seaway, and the slow erosion of its larger mountains - which didn't really change up the selection pressures, so existing species were largely working fine as they were.

During the few times where glaciers completely covered Indiana, the top layers of rock were removed and crushed. As glaciers receded, they left behind massive floodplains, rivers, lakes, and creeks that continued to remove sediment. Take a look at glaciers in Alaska or Greenland that stop on land. At the bottom of the glacier, you always see giant floodplains and streams. In some cases raging rivers.

lol Nico Robin from One Piece donated

[@martinitland]

Of course Nico Robin would be a supporter of a serious archeology oriented channel. (My apologies if this was a case of real and fictional names overlapping, but I just felt it had to be said.)

Finally talking about dinosaurs in Appalachia (landmass)

[@jmg4208]

@3:00 there is geological evidence that eastern & western north-america where separated at one point by a body of water. During what period, can't remember. But YT as great vids on it.

[@AndrewTBP]

The Western Interior Seaway existed from the early Late Cretaceous (100 Ma) to the earliest Paleocene (66 Ma), and it is mentioned & shown in this video, and others by PBS Eons.

I'm sorry, "Nico Robin" at 10:13...? As in the fictional character from the anime One Piece? Or just a coincidental real life person?

[@croceyzx2433]

95% a coincidence lmao

[@onefortheages5983]

the western interior seaway largely disappears by the Maastrichtian, this feels like a worthy note about the implications and mysteries of the refugium reconnecting to laramidia like the The Great American Biotic Interchange millions of years later.

It’s crazy to think how much has simply been lost to time and there’s nothing we can do about it. Even in the places we have tons of dinosaur fossils, there’s probably tons more that never fossilized. At the same time, imagine all the wonderful animals that existed. All the weird dinosaurs, mammals, pterosaurs, anything. There could’ve been ecosystems just as insane as the Morrison or Hell Creek that we’ll never know about.

I LOVE that at the end you acknowledge that many time fossils were on indigenous lands and were “discovered” wrongly. And that you give credit to those Peoples
