They are now assumed to be mostly basal taxa of the charadriiforms and/or "higher waterbirds", which probably were two distinct lineages 65 mya already, [ 16 ] and ...
Four new fossils of Ichthyornis, which had both a beak and teeth and lived a lifestyle like modern gulls, offer striking evidence of this Cretaceous Period bird's important position in avian ...
A living fossil is an extant taxon that phenotypically resembles related species known only from the fossil record. To be considered a living fossil, the fossil species must be old relative to the time of origin of the extant clade. Living fossils commonly are of species-poor lineages, but they need not be.
“We realized we had millions of bones from sea creatures of all sorts, mostly fish, but also sea mammals, sea turtles, shorebirds, kelp and other types of seaweed and invertebrates like shells ...
The following is a list of primitive euornithian genera and those that cannot be confidently referred to any subgroups, following Holtz (2011). [7] †Archaeorhynchus spathula Zhou & Zhang 2006 †Changmaornis houi Wang et al. 2013 †Gargantuavis philoinos Buffetaut & Le Loeuff 1998
Ichthyornis fossils were first unearthed in the 1870s, but the new ones from Kansas and Alabama chalk deposits, reveal far more about it than once known. Ancient bird with beak and teeth blended ...
