Other recent studies (2009) estimate the arrival of fungal organisms at about 760–1060 Ma on the basis of comparisons of the rate of evolution in closely related groups. [13] For much of the Paleozoic Era (542–251 Ma), the fungi appear to have been aquatic and consisted of organisms similar to the extant Chytrids in having flagellum-bearing ...
Prototaxites / ˌ p r oʊ t oʊ ˈ t æ k s ɪ t iː z / is an extinct genus of terrestrial fungi dating from the Late Silurian until the Late Devonian periods. [1] [2] Prototaxites formed large trunk-like structures up to 1 metre (3 ft) wide, reaching 8 metres (26 ft) in length, [3] made up of interwoven tubes around 50 micrometres (0.0020 in) in diameter, making it by far the largest land ...
First sauropod dinosaurs. Diversification in small, ornithischian dinosaurs: heterodontosaurids, fabrosaurids, and scelidosaurids. 190 Ma Pliosauroids appear in the fossil record. First lepidopteran insects (Archaeolepis), hermit crabs, modern starfish, irregular echinoids, corbulid bivalves, and tubulipore bryozoans.
An outcrop of the Cloverly Formation. The Crow people and other Native American groups inhabiting Montana used to use rocks from the Cloverly Formation to make red pigments. . Since the red pigments are richest in the same layers of the formation that preserve dinosaur fossils, it is likely that Native Americans encountered Deinonychus fossils long before scientifically trained paleontolog

Taste was long a barrier to mainstream acceptance of functional mushrooms, says Isokauppila, but product innovation has made these potent fungi easier to swallow. Adaptogenic ‘Shrooms Will Enjoy ...
The history of life on Earth traces the processes by which living and extinct organisms evolved, from the earliest emergence of life to the present day. Earth formed about 4.5 billion years ago (abbreviated as Ga, for gigaannum) and evidence suggests that life emerged prior to 3.7 Ga. [1] [2] [3] The similarities among all known present-day species indicate that they have diverged through the ...
The pterosaur suggests feathers emerged around 250 million years ago through the common ancestor of dinosaurs, birds and pterosaurs -- and shifts the origin of feathers to 100 million years ...
