Natural history museum in LA. They have a big exhibit on theropods and pterosaurs and show the birds that possibly evolved from them. Birds are dinosaurs under all the usual biological classification schemes. Similar phenotypes, similar genotypes.
Are you sure it was "evolved from" and not "looks like"?
Because pterosaurs have no living descents, and all birds descended from therapod dinosaurs (even if birds were already widespread before the end of the Cretaceous).
Yeah it might seem that way but pelicans don't come from pterosaurs.
