Nummulite definition, a fossil foraminifer of the genus Camerina (Nummulites), having a calcareous, usually disklike shell. Nummulites test are radial hyaline, biconvex, planispiral invoulte form that reveal V-shaped cavities in axial section [5]. During the Mesozoic era: the Triassic, Jurassic, and Cretaceous periods. The longest probably being the Supersaurus with its enormous neck. The Eocene Epoch, second of the five epochs into which the Tertiary Period is divided, lasted from 54 to 38 million years ago. Class: Rotaliida. In addition to serving as time markers, foram species are flags of climatic and environmental conditions. Well, I guess a giraffe has very long axon’s coming down its neck. They derive their name from the latin word "nummulus" = small coin, because the frequently appear in disc form.

The δ 18 O depends mainly on the isotope ratio of the water it is precipitated from, the temperature of calcification, and, to a lesser extent, the carbonate ion concentration. If we were only looking at single celled organisms then maybe the Nummulites or the Xenophyophores rarely found only in the depths of the marian trench fit the bill. Updates? It is the period in which Greek and Roman society flourished and wielded great influence throughout Europe, North Africa and the Middle East. Order: Nummulitacea.

If were talking about extinct, then one of the dinosaurs must have had a bigger egg than a bird. A large, coin-shaped foram of the genus Nummulites, widely distributed in limestone formations from the Eocene Epoch to the Miocene Epoch of the Cenozoic. They had complex labyrinthine interiors and internal structural supports to strengthen their adaptation to life in high-energy environments. Also I guess that its how you define a single cell, wether its an organism or part of one and also how you define biggest (longest, largest volume or heaviest). The earliest fusulinids occur in rocks deposited during the late Mississippian Period, more than 323 million years ago. EOCENE, in geology, the name suggested by Sir Charles Lyell in 1833 for the earliest period of the Tertiary era. It is found for the first time in the Late Paleocene toe of slope sediments of a carbonate platform Stratigraphic section D6, Bir Dakhl, Southern Galala, Eastern Desert, Egypt.
