After 1.5 million years ago (extinction of Paranthropus), all fossils shown are human (genus Homo). After 11,500 years ago (11.5 ka, beginning of the Holocene), all fossils shown are Homo sapiens (anatomically modern humans), illustrating recent divergence in the formation of modern human sub-populations.
Life restoration of Confuciusornis sp. with plumage colors and patterns inferred from CUGB P1401 In 2010, Zhang et al. examined fossils of feathered dinosaurs with preserved melanosomes. After studying these with an electron microscope , they found eumelanosomes and pheomelanosomes preserved in a specimen of Confuciusornis , (IVPP V13171).
They restarted excavation of Longlin Cave in 2008, and yielded a few more human fossils, but most of the known material from the cave was recovered in the initial dig. In 2010, they were able to remove the rest of the skull and body fossils from the Red Deer Cave block. [4] The dating of the bones has led to confusion and division among ...
The number of mammaries is now reduced to only one thoracic pair. Platyrrhines, New World monkeys, have prehensile tails and males are color blind. The individuals whose descendants would become Platyrrhini are conjectured to have migrated to South America either on a raft of vegetation or via a land bridge (the hypothesis now favored [27]).
A number of taxa have been described, coming from three different groups: anguimorph and scincomorph lizards and early snakes. [ 26 ] [ 27 ] [ 28 ] The first squamates to be reported from the Morrison Formation were Paramacellodus and Dorsetisaurus , which were described from Wyoming's Quarry 9 by Don Prothero and Richard Estes.

More than 260 dinosaur footprints discovered in Brazil and Cameroon provide further evidence that South America and Africa were once connected as part of a giant continent millions of years ago.
Fossils from La Brea show that Pleistocene coyotes were larger and more robust than their modern relatives and actively hunted larger prey. However, Holocene coyote fossils from Pit 10 already show a decrease in size and change in the anatomy of the mandible, indicating that by this point in time coyotes had begun adapting towards conditions ...
