This list of Mesozoic birds is a comprehensive list of all Mesozoic dinosaurs that have been assigned to the clade Avialae (birds, in the broadest sense). The list includes all commonly accepted genera, but also genera that are now considered invalid, doubtful (nomen dubium), or were not formally published (nomen nudum), as well as junior synonyms of more established names, and genera that are ...
Multituberculata (commonly known as multituberculates, named for the multiple tubercles of their teeth) is an extinct order of rodent-like mammals with a fossil record spanning over 130 million years.
For example, some became aquatic, some were gliders, and some even fed on juvenile dinosaurs. [4] Most of the evidence consists of fossils. For many years, fossils of Mesozoic mammals and their immediate ancestors were very rare and fragmentary; but, since the mid-1990s, there have been many important new finds, especially in China.

The Mesozoic Era [3] is the era of Earth's geological history, lasting from about , comprising the Triassic, Jurassic and Cretaceous Periods.It is characterized by the dominance of archosaurian reptiles such as the dinosaurs, and of gymnosperms such as cycads, ginkgoaceae and araucarian conifers; a hot greenhouse climate; and the tectonic break-up of Pangaea.
Step back in time to the Mesozoic Era, where dinosaurs ruled the Earth. With this quiz, you’ll encounter iconic giants like the T. Rex and the Stegosaurus, clever predators like the Velociraptor ...

For example, mammal jaws have been found in the abdomen of a specimen of the small theropod Sinosauropteryx; the jaws belonged to Zhangheotherium, which also had spurs, and the multituberculate Sinobaatar. Since dinosaurs dominated Earth during the Mesozoic, this period has been called the "dark ages" of mammalian history. The spur, which would ...
