The Library of Congress gets a copy of every book published in the United States, print or digital. It's part of how Copyright is established. It is a RESEARCH library, not one where kids go to check out books.

Without the National Science Foundation, I'd be nothing. NSF funded my PhD on bird origins & later my work on dino extinction & rise of mammals. Now it's being dismantled for pure political reasons. Our country culture & economy will all suffer. Disgraceful! #WithoutNSF #SaveNSF

Despite being marine animals, teleosaurs are even rarer in the Solnhofen Limestones than Dinosaurs. One elusive member of this clade is Aeolodon known by two skeletons, one from Daiting Germany and one from Canjuers france. This clade of teleosaurs was likely pelagic
