Archicebus achilles was named for being the oldest-known primate skeleton (as of 2013) and for its distinguishing calcaneus (heel bone). [5] The generic name, Archicebus, was constructed from arche (ἀρχή), the Ancient Greek word for "beginning", and cebus, the Latin version of the Ancient Greek kêbos (κῆβος), which refers to a long-tailed monkey.
Greatly interested by the finds, Woodward accompanied Dawson to the site. Though the two worked together between June and September 1912, Dawson alone recovered more skull fragments and half of the lower jaw. [3] [4] The skull unearthed in 1908 was the only find discovered in situ, with most of the other pieces found in the gravel pit's spoil ...
Teilhardina (/ t aɪ h ɑːr ˈ d iː n ə /, teye-har-DEE-nuh) [3] is an extinct marmoset-like omomyid primate that lived in Europe, North America and Asia during the Early Eocene epoch, about 56-47 million years ago.
Ni et al., in announcing Archicebus achilles in 2013 as what they describe as the earliest known primate with such detailed remains, place it somewhat differently to the above as they place Omomyids within Tarsiiformes, with Omomyids and Tarsiidae sharing a common ancestor, and that common ancestor sharing a common Tarsiiform ancestor with the ...
Male and female skulls (AMNH 129172/3/4/5) of A. zeuxis. Aegyptopithecus zeuxis was a species that had a dental formula of 2.1.2.3 2.1.2.3, with the lower molars increasing in size posteriorly. The molars showed an adaptation called compartmentalizing shear, which is where the cutting edges involved in the buccal phase serve to surround basins ...
Moyà-Solà et al. initially founded the species on a set of unique characteristics, of which are the following. The frontal processes of the face remain on the same plane, the nasals are flat and sit beneath the lower rims of the orbit, the glabella is posteriorly oriented, the face is low, the brows are thin, the zygomatic root is high, and the nasoalveolar clivus is high.
Tetonus homunculus skull. Anaptomorphinae is a pre-historic group of primates known from Eocene fossils in North America and Europe and later periods of Paleocene Asia, and are a sub-family of omomyids. [2] The anaptomorphines is a paraphyletic group consisting of the two tribes Trogolemurini and Anaptomorphini. [3]
Plesiadapiformes ("Adapid-like" or "near Adapiformes") is an extinct basal pan-primates group, as sister to the rest of the pan-primates. [4] [5] [6] [7] [8] The pan ...
