Fossils many times are more than bones and we get actual imprints of their whole tail or other parts of them
No. This was created by someone who has no idea how any of this work. Soft tissues leave marks on bones.
Soft tissues can also become fossils under the right conditions. For an example, here is the fossil used for the B. markmitchelli holotype:
It’s the single most detailed and complete soft tissue fossil ever discovered. It took the technician six years to extract and separate the fossil from the surrounding stone. The technician’s name is Mark Mitchell, and the species was named after him.
So one of the biggest leaps they have made in reconstruction over the last few decades is matching similar bone structure that supports soft tissue. It doesn’t work for all soft tissue, but if the beavers tail bones have bumps or other features that hint at supporting extra soft tissue there is a chance.
All the stuff birds have, like inflatable neck sacks and feathers that move with muscles are examples of things we absolutely wouldn’t get with fossils that are even better than a beaver tail.
Well, now I want to see an artist’s rendition of a T. rex doing this:
The idea of non-avian dinosaurs with the diverse features and behaviors birds have is very fun to me, and I hope fictitious depictions of birdsaurs becomes as common as classic dinosaurs’s.
I want to see a T. Rex do this.
Also, in 40 million years, you can match the beaver fossils to the bones of their still living descendants and find similar features.
Also the bones need to be in the right position
That is one cute beaver pic on the left. PM more of your beavers.
All dinosaurs had beaver tails, got it!
One thing I wouldn’t mind AI to do, train a model with standardised data like this, and have it match the reconstruction. After that it can use common and less common reconstructions. After that try to map as much info from a dinosaur fossil to said standardised data structure and generate possible reconstruction for said dinosaur
Oh. I like this idea. This is the kind of thing AI would be good for.
Sure but also there are some fossils that DO have skin, and some even have preserved organs. And some have feathers, which is a pretty good indicator that there wasn’t some large feature we’re missing.
No doubt we are wrong on lots of counts, but I think we have good evidence for a lot of it as well.
Do beavers enjoy… Uppies??
Seems so.
I like to imagine T. rex arms were small because that’s how they communicated with their octopus rider.
They evolved to be small so they cold more easily fit into the actuator gauntlets that controlled the Gundam.
They look at related and similarly adapted modern animals when trying to make visualizations of fossils, it’s not all just guessing.
Now I want to see some pics of dinosaurs with beaver tails
What a marvellous time for paleobootyology.
