The Earth has a layered internal structure with the crust, upper mantle, mantle transition zone, lower mantle, outer core, and inner core from the surface to the center. In the Earth’s formation stage at approximately 4.6 billion years ago, the heavy metal components were separated from silicates and sank in the magma ocean, and a core formed at the center of the Earth. In this core-mantle separation process, partitioning of noble gases between the core and mantle occurred. Credit: Taku Tsuchiya, Ehime University

Rafinesquina, seen in this close-up shot, was an ancient genus of brachiopod belonging to order Strophomenida. This order survived two mass extinction events, but the second represented a ‘death sentence’ from which they were unable to recover diversity, persisting for another hundred million years as a ‘dead clade walking’ before their eventual extinction.

Over approximately 2.5 million years, North America likely hosted 2.5 billion Tyrannosaurus rexes, a minuscule proportion of which have been dug up and studied by paleontologists, according to a UC Berkeley study. (Image by Julius Csotonyi, courtesy of Science magazine)

How many T. rexes were there? Billions
