Vertebrates

Fossil of plants, invertebrates, vertebrates, and trace fossils have been identified in Yellowstone National Park from more than 40 stratigraphic units spanning more than 540 million years from the Cambrian to the Cenozoic eras.

Vertebrates typically have teeth.

A paleontologist in Texas has identified a new species of coelacanth, an ancient fish most closely related to land-dwelling vertebrates, including humans.

It may be primitive and not too pleasant, but fish like croakers and toadfish hum, grunt, and growl for the same reasons as other vertebrates: to attract mates and to threaten territorial invaders.

For 135 million years, dinosaurs ruled the Earth as the dominant terrestrial vertebrates, from about 200 million years ago until the cataclysm that wiped them out 66 million years ago.

The article noted that 13,000 years ago, at the end of the Pleistocene geological era, the North American prairie teemed with big vertebrates such as woolly mammoths, five species of horses and an early version of the cheetah.

All higher terrestrial organisms, including humans, other vertebrates, insects and even higher land plants, require complex, fractally branching vascular systems for survival.

All vertebrates are chordates.

Humans, just like fish and birds, are vertebrates.
