This is a 2010 book that reports the status and trends of the world's vertebrates. Mammals, non-avian reptiles, birds, amphibians, and fish (the latter two in a paraphyletic sense) are each given focus here, with the percentage threatened, population trends, and the biggest threats to each group provided.
It should be noted that it's been over a decade since this report was published. From what I can gather, 25,535 species were assessed for this report (at least, that's what Fig. 3 seems to suggest), with 19% of them found to be threatened. As of January 2022, the IUCN Red List has assessed a total of 142,577 species, and of them over 40,000 are threatened. This would mean that 28% of species are threatened, and that the former figure is an underestimate. Of course, that just bolsters the alarming message of this book, and regardless, it is still a good and insightful read.
Infinity Blade: I'm not sure. Freshwater plants certainly grow from the underwater sediment upwards, but I don't know if they support the same kinds of diverse ecosystems seagrass meadows do.

Supercommunist: Is there a freshwater equivalent of seagrass meadows?

roninwolf1981: I wonder why is it that the greater apes would drown if they fell into water from the trees?

Ceratodromeus: Considering even the most terrestrially inclined extant crocodilians are also very good swimmers, i see zero reason for sebechids to not be.

Infinity Blade: Virtually every terrestrial animal can swim if it needs to. I don't know about tail flexibility, though.

jhg: Probably not. Terrestrial crocodiles stayed on land for a good reason.

Supercommunist: Do you think sebecids and other crocodile-like terrestrial animals were good swimmers and if so, would they have used their tails to swim or would they have been too stiff?

Supercommunist: Any idea how well pterosaurs would have fared in extremely cold climates? I can't help but assume that their wing membranes would be more vunerable to frostbite than a bird's wing.

Supercommunist: Turns out there is a study: www.nature.com/articles/s41598-017-08812-2 fresh bones provided 63% more energy than dry bones but what I find intresting is that dry bones that are between 3-12 months old is still a viable food source for them.

Infinity Blade: I think they might get calcium from the bones, but those might be harder to digest as well. For bone marrow, I'd say however long it's around before it completely decays.

Supercommunist: Question: I know a bearded vulture's diet consists mainly of bone marrow, but are they able to derive nutritional value from old bones or do the bones have to be relatively fresh?
