Ichthyornis (meaning "fish bird", after its fish-like vertebrae) is an extinct genus of toothy seabird-like ornithuran from the late Cretaceous period of North America.Its fossil remains are known from the chalks of Alberta, Alabama, Kansas (Greenhorn Limestone), New Mexico, Saskatchewan, and Texas, in strata that were laid down in the Western Interior Seaway during the Turonian through ...
There is a two-way interplay between human attitudes, beliefs, and symbols concerning fish, such as in Christianity, and people's practical use of and dependency on fish: "Fish not only guarantee the necessities of human life as food for the world, but they also establish human and fish relationships that link social, cultural, traditional, and ...

In the sea, the bony fish became dominant. The later radiations, such as those of fish in the Silurian and Devonian periods, involved fewer taxa, mainly with very similar body plans. The first animals to venture onto dry land were arthropods. Some fish had lungs and strong, bony fins and could crawl onto the land also.
The North American bird population has dropped nearly 3 billion birds, or 30%, since 1970, according to a study by the Cornell Lab of Ornithology. "We just need to make sure, in the end, of ...
Many were coastal birds, strikingly resembling modern shorebirds, like Ichthyornis, or ducks, like Gansus. Some evolved as swimming hunters, like the Hesperornithiformes – a group of flightless divers resembling grebes and loons. While modern in most respects, most of these birds retained typical reptilian-like teeth and sharp claws on the manus.
He also argued that the first human of the form known today must have been the child of a different type of animal (probably a fish), because man needs prolonged nursing to live. [8] [9] [7] In the late nineteenth century, Anaximander was hailed as the "first Darwinist", but this characterization is no longer commonly agreed. [10]
