Aquatic Dinosaur Tapestries
Description: A black background features the word BIOLOGY in bold blue letters within a blue rectangle. Below, a line of white and blue silhouettes depicts the evolution of life, starting with primitive aquatic organisms, transitioning through ape-like figures, dinosaurs, trees, a mammoth, and ending with a modern human silhouette.
Description: Hesperornis (meaning "western bird") is a genus of flightless aquatic birds that spanned the first half of the Campanian age of the Late Cretaceous period (83.5–78 mya). One of the lesser-known discoveries of the paleontologist O. C. Marsh in the late 19th century Bone Wars, it was an early find in the history of avian paleontology. Locations for Hesperornis fossils include the Late Cretaceous marine limestones from Kansas and the marine shales from Canada. Nine species are recognised, eight of which have been recovered from rocks in North America and one from Russia.
Description: The coelacanths (SEE-lə-kanth) constitute a now rare order of fish that includes two extant species in the genus Latimeria: the West Indian Ocean coelacanth (Latimeria chalumnae) primarily found near the Comoro Islands off the east coast of Africa and the Indonesian coelacanth (Latimeria menadoensis). They follow the oldest known living lineage of Sarcopterygii (lobe-finned fish and tetrapods), which means they are more closely related to lungfish, reptiles, and mammals than to the common ray-finned fishes.
