Lord help us all.... #Paleontologists and #astrophysicists, get a load of this one. Apparently y'all just guess and fabricate stories to explain stuff you don't know. 🤦🏻‍♀️🤦🏻‍♀️🤦🏻‍♀️🤦🏻‍♀️🤦🏻‍♀️

Paleontologists have found early examples of theropods, the group that would eventually include tyrannosaurs. But precisely how another group of dinosaurs, known as the bird-hipped ornithischians, evolved remains a major question in paleontology. Image credit: Roger Harris / SPL via Getty Images

Oldest fossilized dinosaur vomit discovered in Germany The Paleozoic 'regurgitalite' is over 290 million years old.

#Regurgitalite seems to be an appropriate word to think about now. Many people I know are doing it. It's an interesting process #paleontologists go through sort out what it is and I wonder what future scientists would learn about my cats if theirs was preserved.

How Is It Possible For Dinosaur Footprints To Fossilize And Endure For Millions Of Years? Dinosaur fossil footprints have yielded remarkable insights into these extinct animals’ behaviors, revealing evidence of everything from running speed to migration and even swimming. They’re a bit odd as fossils go, representing the memory of something rather than containing a bit of an actual animal. So, how is it that dinosaur footprints fossilize, enduring for millions of years? Footsteps fall under an area of palaeontology known as ichnology, which looks at fossilized traces like trackways, butt drags, and lek scratches. Such fossils can reveal a lot about dinosaur behavior if you know how to read them, and the process that preserves their prints isn’t unique to dinosaurs. “We think of footprints as things that don't last very long, but as someone even looking for dinosaurs walking around the desert, I can find footprints from people who passed the same way years before,” said science writer and palaeontologist Riley Black to IFLScience in an episode of The Big Questions about dinosaur sex. “They might not always be the highest resolution, but in the right situations, in the right circumstances, where you have a wet sediment that's able to take the shape of the foot that becomes dried out, then covered over, you're basically recreating a mold and cast naturally.” Imagine yourself walking along a riverbank. The water has recently receded, leaving behind a muddy bit at the river’s edge. You look behind you and see a trail of your footprints. Probably not going to be there tomorrow, right? But what if that patch stays dry long enough for the Sun to come out and dry it up. That mud could then hold its shape, and when it rains or the river’s levels rise again, it washes new sediment into the print you have made. That fresh sediment could also get baked by the Sun and harden. Leap forward a few million years and through the process of being pressed, becoming rock, and getting raised, some keen-eyed citizen scientist finds the fossilized ancient footprint and its counterpart. “You basically wind up with a mold and a cast, much like you might make with plaster of Paris,” said Black. “It's more or less the same concept." “That's how so many of these traces become preserved. So, it's really remarkable that they can be preserved at all, that all these moments where these things would otherwise have eroded away and would just disappear most of the time, [that instead] that’s what happened.” We’ve been lucky to uncover countless dinosaur footprints over centuries of exploration, some of which represent the largest dinosaur trackways known to science. Remarkable to think, then, that they represent such a miniscule snapshot of a period in geological time, as most animals that ever lived on this planet will leave nothing behind. “It's the same thing as fossil bones,” said Black. “We think of bones and things as sturdy, but they still require relatively rapid burial. They still need to be protected within the sediment to be preserved, and the same principles are at play with ichnology as well.” So, if you want to leave some footprints behind, best get stomping along some riverbeds. And if you want to become a fossil? Well, that’s going to require a bit more planning.

#Dinosaur footprints are a great source of discovery for #paleontologists, and there's science behind how they have been able to fossilize and endure for ages.

#Paleontologists, was there ever a crab, that evolved away from being a crab, that evolved again back into being a crab?

Driving around doing #fieldwork recently, I very much enjoyed listening to Neil Shubin's book YOUR INNER FISH. With lessons for all humans interested in the origins of their body parts, I especially enjoyed getting glimpses into the work of #fossil preparers, #paleontologists and human anatomists.

#paleontologists, how do we know that some dinosaurs had excellent color vision? What have y’all been up to to figure this out? #otherlands

... size if sufficiently large, so there would be an evolutionary advantage to them growing over time until they started to fulfil the function of gliding and then, subsequently, flight.

Any #paleontologists out there?

Any #paleontologists that can weigh in on this?

I was thinking if hadrosaurs had a more efficient metabolism/food-to-meat conversion, I strongly believe we could farm smaller species like cattle. Would their meat be more reptile, bird, or like steak?
