Kannemeyeria is a genus of kannemeyeriid dicynodont that lived during the Anisian age of Middle Triassic period in what is now Africa and South America. The generic name is given in honor of Dr. Daniel Rossouw Kannemeyer, the South African fossil collector who discovered the original specimen. It is one of the first representatives of the family, and hence one of the first large herbivores of the Triassic.

Megistotherium
Megistotherium. Roman Yevseev
Name: Megistotherium (Greek for "largest beast"); pronounced meh-JISS-toe-THEE-ree-um
Habitat: Plains of North Africa
Historical Epoch: Early Miocene (20 million years ago)
Size and Weight: About 12 feet long and 1,000-2,000 pounds
Diet: Meat
Distinguishing Characteristics: Large size; elongated skull with powerful jaws
You can get the true measure of Megistotherium by learning its last, i.e., species name: "osteophlastes," Greek for "bone-crushing." This was the biggest of all the creodonts, the carnivorous mammals that preceded modern wolves, cats and hyenas, weighing close to a ton and with a long, massive, powerfully jawed head. As big as it was, though, it's possible that Megistotherium was unusually slow and clumsy, a hint that it may have scavenged already-dead carcasses (like a hyena) rather than actively hunting down prey (like a wolf). The only megafauna carnivore to rival it in size was Andrewsarchus, which may or may not have been substantially bigger, depending on whose reconstruction you believe.

Nothosaur
en.wikipedia.org
Nothosaurs (order Nothosauroidea) were Triassic marine sauropterygian reptiles that may have lived like seals of today, catching food in water but coming ashore on rocks and beaches. They averaged about 3 metres (10 ft) in length, with a long body and tail.[1] The feet were paddle-like, and are known to have been webbed in life, to help power the animal when swimming.

Oxalaia (in reference to the African deity Oxalá) is a genus of spinosaurid dinosaur that lived in what is now the Northeast Region of Brazil during the Cenomanian stage of the Late Cretaceous period, sometime between 100.5 and 93.9 million years ago. Its only known fossils were found in 1999 on Cajual Island in the rocks of the Alcântara Formation, which is known for its abundance of fragmentary, isolated fossil specimens. The remains of Oxalaia were described in 2011 by Brazilian palaeontologist Alexander Kellner

Plate Tectonics
en.wikipedia.org
Evidence of the details of plate motions and other tectonic activity in the Precambrian has been poorly preserved. It is generally believed that small proto-continents existed prior to 4280 Ma, and that most of the Earth's landmasses collected into a single supercontinent around 1130 Ma. The supercontinent, known as Rodinia, broke up around 750 Ma. A number of glacial periods have been identified going as far back as the Huronian epoch, roughly 2400–2100 Ma. One of the best studied is the Sturtian-Varangian glaciation, around 850–635 Ma, which may have brought glacial conditions all the way to the equator, resulting in a "Snowball Earth".

Radiation
The extinction of nearly all animal species at the end of the Permian period allowed for the radiation of many new lifeforms.

Smilodon is a genus of the extinct machairodont subfamily of the felids. It is one of the most famous prehistoric mammals and the best known saber-toothed cat. Although commonly known as the saber-toothed tiger, it was not closely related to the tiger or other modern cats. Smilodon lived in the Americas during the Pleistocene epoch (2.5 mya – 10,000 years ago).

Uintatherium
One of the first prehistoric megafauna mammals ever to be discovered, in late-nineteenth-century Wyoming, Uintatherium figured in the "Bone Wars" waged between the famous American paleontologists Edward Drinker Cope and Othniel C. Marsh. This bizarre, plant-eating beast was worth a good fight.

Yunnanocephalus Fossil is a genus of ptychopariid trilobite. It lived during the late Atdabanian and Botomian stages, in what are currently Antarctica, Australia and China. It was a "moderately common" member of the Chengjiang Fauna. Yunnanocephalus is the only genus currently assigned to the Yunnanocephalidae family.

Bacteria
en.wikipedia.org
A specific date for the origin of life has not been determined. Carbon found in 3.8 billion-year-old rocks (Archean eon) from islands off western Greenland may be of organic origin. Well-preserved microscopic fossils of bacteria older than 3.46 billion years have been found in Western Australia. Probable fossils 100 million years older have been found in the same area. However, there is evidence that life could have evolved over 4.280 billion years ago. There is a fairly solid record of bacterial life throughout the remainder (Proterozoic eon) of the Precambrian.
