The pterodactyloids were actually a large suborder of avian reptiles that included such creatures as Pteranodon, Pterodactylus and the truly enormous Quetzalcoatlus, the largest winged animal in earth's history; pterodactyloids were anatomically different from the earlier, smaller "rhamphorhynchoid" pterosaurs that dominated the Jurassic period.

During the first three thousand years of what scholars recognize as the Mesolithic, a period of climatic instability made life difficult in Europe, with gradual warming abruptly switching to 1,200 years of very cold dry weather called the Younger Dryas.

Counting can seem like an easy task to perform. As we go deeper into the area of mathematics known as combinatorics, we realize that we come across some large numbers. Since the factorial shows up so often, and a number such as 10! is greater than three million, counting problems can get complicated very quickly if we attempt to list out all of the possibilities.
Tropical rainforests mainly occur in the World's equatorial regions.

They are also located on major separate continental forests which preserve them as independent, non-contiguous realms.

A centromere is a region on a chromosome that joins sister chromatids. Sister chromatids are double-stranded, replicated chromosomes that form during cell division. The primary function of the centromere is to serve as a place of attachment for spindle fibers during cell division. The spindle apparatus elongates cells and separates chromosomes to ensure that each new daughter cell has the correct number of chromosomes at the completion of mitosis and meiosis.
