It's a 40 minute video but it's so informative.
Two history YouTubers; Milo 'Miniminuteman' Rossi, an environmental scientist, archaeologist, and science educator, and Lindsay Nikole, a zoologist, go behind the scenes at the La Brea Tar Pits in Los Angeles, seeing how the site treats the fossils recovered from the crude oil from the tar pits, how they're stored, along with a brief showing of the near three MILLION fossils recovered from the site during its over century long history of excavation at the site, which includes the likes of Columbian mammoths, dire-wolves, short-faced bears, giant ground sloths, sabre-toothed cats, ancient horses and bison, and a lot more.
Now, I know not a whole lot about how fossils are formed in the La Brea Tar pits, but the way they form in the tar and asphalt is so different to just regular fossilization wherein the bones turn to stone, because these are as close to actual bones as people can get. There's still protein in the bones! And it's not just the bones themselves that are of scientific interest, but the asphalt that the bones are found in are of interest as well, as we see in the video where, once a bone is denuded of the asphaltic matrix, the matrix is kept and then basically gone through with a fine tooth comb to find stuff within like insects, shell, flora and even just sand itself, so as to better investigate the conditions of prehistoric Los Angeles.
