Largest Prehistoric Animals
The largest prehistoric animals include both vertebrate and invertebrate species. Many of them are described below, along with their typical range of size (for the general dates of extinction, see the link to each). Many species mentioned might not actually be the largest representative of their clade due to the incompleteness of the fossil record and many of the sizes given are merely estimates since no complete specimen have been found. Their body mass, especially, is largely conjecture because soft tissue was rarely fossilized. Generally the size of extinct species was subject to energetic and biomechanical constraints. Non-mammalian synapsids (Synapsida) Caseasaurs (Caseasauria) The herbivorous ''Alierasaurus'' was the largest caseid and the largest amniote to have lived at the time, with an estimated length around . '' Cotylorhynchus hancocki'' is also large, with an estimated length and weight of at least and more than . Edaphosaurids (Edaphosauridae) The larges ...

Patagotitan Vs Mammals Scale Diagram SVG Steveoc86
''Patagotitan'' is a genus of titanosaurian sauropod dinosaur from the Cerro Barcino Formation in Chubut Province, Patagonia, Argentina. The genus contains a single species known from multiple individuals: ''Patagotitan mayorum'', first announced in 2014 and then validly named in 2017 by José Carballido, Diego Pol, and colleagues. Contemporary studies estimated the length of the type specimen, a young adult, at with a weight estimated at , later revised to . Discovery Remains of ''Patagotitan mayorum'', a part of a lower thighbone, were initially discovered in 2008 by a farm laborer, Aurelio Hernández, in the desert near La Flecha, Argentina, about west of Trelew. Excavation was done by palaeontologists from the Museum of Paleontology Egidio Feruglio. The lead scientists on the excavation were Jose Luis Carballido and Diego Pol, with partial funding from The Jurassic Foundation. Between January 2013 and February 2015, seven paleontological field expeditions were carr ...

Dinocephalia
Dinocephalians (terrible heads) are a clade of large-bodied early therapsids that flourished in the Early and Middle Permian between 279.5 and 260 million years ago (Ma), but became extinct during the Capitanian mass extinction event. Dinocephalians included herbivorous, carnivorous, and omnivorous forms. Many species had thickened skulls with many knobs and bony projections. Dinocephalians were the first non-mammalian therapsids to be scientifically described and their fossils are known from Russia, China, Brazil, South Africa, Zimbabwe, and Tanzania. Description Apart from the Biarmosuchians, the dinocephalians are the least advanced therapsids, although still uniquely specialised in their own way. They retain a number of primitive characteristics (e.g. no secondary palate, small dentary) shared with their pelycosaur ancestors, although they are also more advanced in possessing therapsid adaptations like the expansion of the ilium and more erect limbs. They include carni ...

Eotitanosuchus
''Eotitanosuchus'' ("dawn giant crocodile") is an extinct genus of biarmosuchian therapsids whose fossils were found in the town of Ochyor in Perm Krai, Russia. It lived about 267 million years ago. The only species is ''Eotitanosuchus olsoni''. Description ''Eotitanosuchus'' is known from a single large skull without a lower jaw. The skull was , but the overall length may have been over , possibly up to and more than in weight for adult specimens. Like ''Biarmosuchus tener'', it was primitive in that, though it was a predator, the temple opening behind the eye was small, giving it a weak bite. The temple was, however, larger at the top than in other biarmosuchians. Paleoecology ''Eotitanosuchus'' fossils were found in the Perm (or Cis-Urals) region of Russia. ''Eotitanosuchus'' was without doubt a dominant animal of its environment. Found preserved in flood deposits (once coastal bogs) containing many skeletons of estemmenosuchids, it has been suggested that this large preda ...

Anteosauridae
Anteosauridae is an extinct family of large carnivorous dinocephalian therapsids that are known from the Middle Permian of Asia, Africa, and South America.These animals were by far the largest predators of the Permian period, with skulls reaching 80 cm in length in adult individuals, far larger than the biggest gorgonopsian. Description Anteosaurids are characterized by very large pointed incisors and canines, bulbous spatulate (spoon shaped) postcanines, a very strongly upturned margin of the premaxilla, so the front of mouth curves strongly upwards, and a long, very robust lower jaw (Boonstra 1963). Anteosaurids distinguished from ''Brithopus'' and other non-anteosaurid anteosaurians by the presence of a large thickened region or "boss" on the side of the angle of the lower jaw; this was probably used in intraspecific behaviour. In '' Doliosauriscus'' and ''Anteosaurus'', not only was this boss very prominent, but the bones were very thick and rugose. The same situation ...

Titanophoneus
''Titanophoneus'' ("titanic murderer") is an extinct genus of carnivorous dinocephalian therapsid from the Middle Permian. It is classified within the family Anteosauridae. The type species is ''Titanophoneus potens''. Remains of ''Titanophoneus'' have been found at Isheevo in Russia. Description An adult skull would have reached 80 cm with a heavy long snout. The long tail and short limbs show the species to be a primitive therapsid unlike '' Inostrancevia'' which was more advanced. The structure of the limbs and the density of the bone are designed for a sprawling stance. The temporal opening is more advanced than Estemmenosuchidae but less advanced than ''Inostrancevia''. The teeth are large with 12 large palate incisors followed by 2 canines and various smaller back teeth. The lower palate is the same as the upper but without the canine teeth. The appearance of ''Titanophoneus'' is reminiscent to the sphenacodontid pelycosaurs, which included ''Dimetrodon''. Gallery im ...

Anteosaurus
''Anteosaurus'' (meaning "Antaeus reptile") is an extinct genus of large carnivorous dinocephalian synapsid. It lived at the end of the Guadalupian (= Middle Permian) during the Capitanian stage, about 265 to 260 million years ago in what is now South Africa. It is mainly known by cranial remains and few postcranial bones. With its skull reaching in length and a body size estimated at more than in length, and in weight, ''Anteosaurus'' was the largest known carnivorous non-mammalian synapsid and the largest terrestrial predator of the Permian period. Occupying the top of the food chain in the Middle Permian, its skull, jaws and teeth show adaptations to capture large prey like the giants titanosuchids and tapinocephalids dinocephalians and large pareiasaurs. As in many other dinocephalians the cranial bones of ''Anteosaurus'' are pachyostosed, but to a lesser extent than in tapinocephalid dinocephalians. In ''Anteosaurus'', pachyostosis mainly occurs in the form of horn-sha ...

Science Daily
''Science Daily'' is an American website launched in 1995 that aggregates press releases and publishes lightly edited press releases (a practice called churnalism) about science, similar to Phys.org and EurekAlert!. The site was founded by married couple Dan and Michele Hogan in 1995; Dan Hogan formerly worked in the public affairs department of Jackson Laboratory writing press releases. The site makes money from selling advertisements. As of 2010, the site said that it had grown "from a two-person operation to a full-fledged news business with worldwide contributors". At the time, it was run out of the Hogans' home, had no reporters, and only reprinted press releases. In 2012, Quantcast Quantcast is an American technology company, founded in 2006, that specializes in AI-driven real-time advertising, audience insights and measurement. It has offices in the United States, Canada, Australia, Singapore, United Kingdom, Ireland, Fran ... ranked it at 614 with 2.6 million U.S. vi ...
