Smithsonian Museum of Natural History: Hall of Fossils, part 3

The event that defined the beginning of the rise of Mammal-ascendancy is also the one that divides their presentation at the Smithsonian Museum of Natural Histories, Hall of Fossils: Deep Time exhibition.  66 million years ago the meteor that stuck near the present day, Yucatan Peninsula in Mexico sets the clock for the beginning of the next section focused on Dinosaurs and the world they reigned over.

 The skeleton of a T-Rex poised over the vanquished skeleton of a Triceratops.  Glare of the glass unfortunate and ubiquitous throughout the exhibit (and the museum, for that matter...)

"Floodplains Full of Life" time capsule.

Diorama details (above and below)

 Diplodocus, the long-necked wonder of the late Mesozoic Era.

Brachiosaurus, no slouch in the Dinosaur size department!

A juvenile Pachysaurus, a great reminder that the giants all started as something much smaller. 

 A prehistoric "etendre" captured in stone, graceful in death for the delight and wonder of creatures inconceivable to this ancient "dancer".

 A Stegosaurus, and early superstar of the Mesozoic Era.

 Wonders from the ancient oceans captured like photographs in sandstone.
