Mesozoic Era, second of Earth’s three major geologic eras of Phanerozoic time. Its name is derived from the Greek term for “middle life.” The Mesozoic Era began 252.2 million years ago, following the conclusion of the Paleozoic Era, and ended 66 million years ago, at the dawn of the Cenozoic Era.(See the geologic time scale.)The major divisions of the …By the end of the Cretaceous Period however, extinction had wiped out the ammonoids entirely and left only one surviving nautiloid clade, the genus Nautilus. Today, the only living representatives of shelled cephalopods are a few species of Nautilus. These molluscs are slow-moving, restricted to deep water, and have coiled shells that are ...That is, about half of all ammonite species from this time are found in only one or two spots. And the more exquisite the ammonite's niche, the less likely it was to survive the Cretaceous apocalypse.

Triassic ammonoid genera (spanning ~166 Myr) shows that eight basic morphotypes appeared within ~20 Myr of the first appearance of ammonoids.In 734 BC the Ammonite king Sanipu was a vassal of Tiglath-Pileser III of Assyria, and Sanipu's successor Pudu-ilu held the same position under Sennacherib (r. 705–681) and Esarhaddon (r. 681–669). An Assyrian tribute-list exists from this period, showing that Ammon paid one-fifth as much tribute as Judah did.Paleozoic ammonoids showed remarkable diversity in the morphology of the internal septa that subdivide the shell into a series of chambers, despite a notable lack of innovation in external shell geometry over the same time period (Saunders et al., 2004).

Abstract. The latitudinal distributions in Devonian-Cretaceous ammonoids were analyzed at the genus level, and were compared with the hatchling sizes (i.e., ammonitella diameters) and the geological durations. The results show that (1) length of temporal ranges of ammonoids effected broader ranges of fossil distribution and paleobiogeography of ...Ammonoids are a group of extinct marine mollusc animals in the subclass Ammonoidea of the class Cephalopoda. ...
