The chimpanzee–human divergence likely took place around 10 to 7 million years ago. [1] The list of fossils begins with Graecopithecus, dated some 7.2 million years ago, which may or may not still be ancestral to both the human and the chimpanzee lineage.
Scientists in Argentina have discovered excellently preserved fossil remains of the oldest-known tadpole, the larval stage of a large frog species that lived alongside dinosaurs about 161 million ...
General patterns of dental morphological evolution throughout human evolution include a reduction in facial prognathism, the presence of a Y5 cusp pattern, the formation of a parabolic palate and the loss of the diastema. Human teeth are made of dentin and are covered by enamel in the areas that are exposed. [2]
Beelzebufo (/ b iː ˌ ɛ l z ɪ ˈ b juː f oʊ / or / ˌ b iː l z ə ˈ b juː f oʊ /) is an extinct genus of hyloid frog from the Late Cretaceous Berivotra and Maevarano Formations of Madagascar. [1] The type species is B. ampinga, and common names assigned by the popular media to B. ampinga include devil frog, [2] devil toad, [3] and the ...
Kermit the Frog meet Kermitops gratus, the most recent ancient amphibian to be identified after examination of a tiny fossilized skull that once sat unstudied in the Smithsonian fossil collection ...
The degree of tooth development found in the Jebel Irhoud hominins is similar to that of modern European children of the same age, but teeth roots develop faster than for modern humans (and slower than for apes and some other fossil hominids). Tooth crowns took a longer time to form than in modern humans. [31]
Paleoanthropologists unearthed human fossils suggesting that the species left Africa at least 50,000 years earlier than previously thought.
Having no hard skeletons, it might be expected that tadpole fossils would not exist. However, traces of biofilms have been preserved and fossil tadpoles have been found dating back to the Middle Jurassic. [1] Tadpoles are eaten as human food in some parts of the world and are mentioned in various folk tales from around the world.
