An andrewsarchus is an extinct mammal belonging to the Eocene epoch.
Well first Andrewsarchus wasn't a dinosaur or a reptile it was a placental mammal that lived after the dinosaurs during the ice age.
Andrewsarchus was a very large species of carnivorous mammal that lived 35 million years ago in Mongolia. There is much debate on whether it was primarily a scavenger or a predator, based on the shape of it's upper jaw. It was also possibly the largest carnivorous mammal to ever live.
andrewsarchus might have gone extinct during the central Asian extinction caused by the formation of the Himalaya Mountains 40 million tears ago or because of Habitat loss maybe Global warming and Climate change
Andrewsarchus was a carnivorous mammal that lived during the late Paleocene to early Eocene epochs. It is believed to have primarily fed on other animals, possibly including large prey due to its size and dental structure, which suggests a diet of flesh. Its exact feeding habits remain somewhat speculative, but it likely occupied a top predator role in its ecosystem.
I really hate to say it but this is a rather pointless question. Tyrannosaurus-rex was 18-20 feet tall on average. While a Saber toothed Tiger was only about 6-7 feet long at not even taller than a human. So T-rex could kill the tiger with 1 bite or just crush it a few times with it's feet.
Do you mean instinct?If you do,then here are a few examples: -Mammoth -Sabertooth Tiger -Woolly Rhino -Cave Lion -Chalicotherium -Andrewsarchus -Baluchitherium -Doedicurus -Glyptodon -Mastodon & -Megatherium Remember,those are just a FEW examples.There are thousands more and I would not like to put them all on here:)
Some prehistoric mammals that start with the letter "A" include the Andrewsarchus, a large carnivorous mammal from the Eocene epoch, and the Aelurodon, an extinct genus of canid resembling modern-day wolves. Additionally, the Arctocyon, an early mammal from the Paleocene, is notable for its unique adaptations. These creatures provide valuable insights into the evolution of mammals.
The largest carniverous animal in the ocean in the Great White shark. It can grow up to 6m(20ft)in length & 2,268 kilograms(5,000 lb)in weight. It reaches maturity at around 15 years of age and can have a life span of over 30 years. :D The largest terrestrial carniverous animal in the eocene was called Andrewsarchus and was 6 metres in length.
Andrewsarchus possibly the largest land-dwelling carnivorous mammal known ever to exist. Lived 45-36 million years ago.Had a length from the snout to the back of the pelvis of about 3.4 m and a height from the ground to the shoulder or middle of the back of about 1.8 m. Weighted about 1000-1800 kg.
The truth is that we really can't be sure what kind of abnormal and fearsome predatory animals lived tens of thousand of millions of year ago.The fossilization process of dead animals (and plants) is VERY, VERY rare.We only have fossils of the most diversified and cosmopolitan species of life in prehistorical times. An I will not even mention the science ignorance about the strange life forms from precambrian ages!We only know the tip of the iceberg.Paleontology is finding, every year, new and surprising evidences of animals we have never dreamed could have ever existed, from the Phanerozoic eon but also from the Cryptozoic supereon.So, don't be surprised when we will find, in short term, fossils of predatory animals that would dwarf the Andrewsarchusand the Spinosaurus...«Life forms in Earth's past is not only stranger than we imagine.It is stranger than we could have ever imagined.»
The Cenozoic Era started 65.5 million years ago and still is the current era. It is widely recognised as the era of the mammal but this is a very simplistic view. For several million years after the KT-Event the most dominant animals where the Terror Birds. In South America this dominance only ended about 2 million years ago soon after it joined with North America and species of saber toothed cats took over. From as long ago as 45 million years ago mammals such as Andrewsarchus on land and Basilosaurus in the oceans had come to dominate most environments on Earth. One major exception to mammalian domination is flying animals. The sky during the Cenozoic has been mainly dominated by the decedents of dinosaurs, the birds. Other smaller environments such as the everglades in southern Florida the dominant animals are the Reptilian Alligators. One mammal however has become the most dominant species on earth, Human Beings. Starting from about 200,000 years we started to slowly dominate Africa and about 70,000 years ago we started to colonise the rest of the planet. We now are the most dominant species in every environment.
The Cenozoic started 65.5 million years ago, and it continues through the present day. The Cenozoic is when flowering plants and mammals diversified and came to dominate terrestrial flora and fauna, respectively. Mammals started out small, but evolved into all the forms that exist today, from elephants to lions to kangaroos to bats to sea lions.
