Evidence of possibly the oldest forms of life on Earth has been found in hydrothermal vent precipitates. [1]The earliest known life forms on Earth may be as old as 4.1 billion years (or Ga) according to biologically fractionated graphite inside a single zircon grain in the Jack Hills range of Australia.

It is claimed to be the oldest animal fossil, being found in rock aged between 760 and 550 million years ago. The genus was named after the Otavi Group in Namibia in which the fossils were found. The oldest fossils are from the Tonian period, before the Cryogenian glaciations, but the latest found were from the Nama Group rocks, which are from ...
Practically all deep-ocean crust present during the Triassic has been recycled through the subduction of oceanic plates, so very little is known about the open ocean from this time period. Most information on Panthalassan geology and marine life is derived from island arcs and rare seafloor sediments accreted onto surrounding land masses, such ...
A 68-million-year-old skull fossil found in Antarctica has revealed the oldest known modern bird, which was likely related to the waterfowl that live by lakes and oceans today, according to new ...
The oldest known fossils of grasses are from the Albian, [87] with the family having diversified into modern groups by the end of the Cretaceous. [88] The oldest large angiosperm trees are known from the Turonian (c. 90 Mya) of New Jersey, with the trunk having a preserved diameter of 1.8 metres (5.9 ft) and an estimated height of 50 metres ...
Incredibly well-preserved fossils of the oldest swimming jellyfish, which lived 505 million years ago, were discovered at a famed fossil site in Canada. ... which lived in Earth’s oceans 505 ...
A massive jawbone found by a father-daughter fossil-collecting duo on a beach in Somerset along the English coast belonged to a newfound species that’s likely the largest known marine reptile to ...
The Miocene (/ ˈ m aɪ. ə s iː n,-oʊ-/ MY-ə-seen, -oh-) [6] [7] is the first geological epoch of the Neogene Period and extends from about (Ma). The Miocene was named by Scottish geologist Charles Lyell; the name comes from the Greek words μείων (meíōn, "less") and καινός (kainós, "new") [8] [9] and means "less recent" because it has 18% fewer modern marine invertebrates ...
