In your entire life, have you ever seen anything or something big? Or maybe animals that are very large.
Like the following 10 animals that supposedly said to have existed and lived on Earth. Their size is very large. What animals? Following the review,
1. Titanoboa
Titanoboa (Boa Titan) is a snake genus that lived about 60 to 58 million years ago in the Paleocene period. The only species in this genus known is Titanoboa cerrejonensis, the largest snake ever encountered. Scientists estimate T. cerrejonensis has a length of 13 m with a mass of more than 1,100 kg, and has a width of 1 m. The fossil 28 T. cerrejonensis was discovered in the Cerrejón coal mine in northern Colombia in 2009.
2. Sarcosuchus
Sarcosuchus (meaning 'crocodile meat' and commonly called "SuperCroc") is an extinct crocodyliform genus and is relatively far from crocodiles. This fossil comes from the early Cretaceous Period which is now Africa and is one of the largest giant crocodile-like reptiles that ever existed. Its size is almost twice the length of saltwater crocodiles now and it weighs around 8-10 tons. Until recently, all that was known from the genus were several fossil teeth and armor scutes, which were discovered in the Sahara Desert by French paleontologist Albert-Félix de Lapparent, in the 1940s or 1950s. However, in 1997 and 2000, Paul Sereno discovered half a dozen new specimens, including one with about half an intact skeleton and most of the spine. All other giant crocodiles are known only from a few partial skulls, so the biggest is actually an open question. As an adult, Sarcosuchus is believed to be able to have a city bus length (11.2-12.2 meters or 37-40 feet) and weigh up to 8 tons (8.75 tons).
3. Amficoelia
In this genus there was once a herbivorous sauropod (Sauropodomorpha) which may be one of the largest dinosaurs in history, namely Amphicoelias fragillimus, which could possibly reach 40-60 meters in length, as well as rival the largest animal on earth, the blue whale. Even so, the fossils from Amphicoelias found were only fossils of their feet, so they were not officially the largest animals. For the time being, only argentinosaurus was officially the skeleton found, although only fossil skulls have never been found.
However, based on the results of studies in 2018, this species was moved into a new genus called Maraapunisaurus.
4. Argentavis
Argentavis magnificens was among the largest flying birds ever to exist, quite possibly surpassed in wingspan only by Pelagornis sandersi, which was described in 2014. A. magnificens, sometimes called the Giant Teratorn, is an extinct species known from three sites in the Epecuén and Andalhualá Formations in central and northwestern Argentina dating to the Late Miocene (Huayquerian), where a good sample of fossils has been obtained.
5. Merostomes
Embryology] and one of Brauer's figures. Study of these shows that the carapaces of the larval eurypterids have a closer agreement with Early stage in development of scorpion. Ventral view of embryo. af, eye fold; sa, lateral eyes; obl, upper lip; Km, comb (pecten); abp, abdominal legs (gills). (From Brauer)Limulus than with the scorpions. In the scorpion embryo and larvae the carapace is relatively of larger size than in the eurypterids, being nearly half the length of the embryo, but it is long and slender, instead of short and broad or semicircular as in the merostomes; the procephalic region early, exhibits a deep frontal emargination and, according to Metschnikoff, a distinct bilobation, features that are found in neither Limulus nor the eurypterids, but which are characters of the adult scorpion.
Likewise the development of the cephalothoracic appendages, while homologous in number and original position as to the stomodaeum (embryonic mouth) to that of the merostomes, differs from that of the eurypterids and Limulus in the early development of the pedipalps of the second segment, corresponding to their prominence in the adult scorpion. They are even recognizable earlier than the chelicerae of the first segment, while the following four pairs of walking legs are of uniform size and character.
6. Giant bear
Ancient bear fossils found in the Canadian High Arctic show that the mammal had a serious sweet tooth. Researchers found evidence of significant tooth decay among the remains of 3.5 million years.
Fossils belong to an extinct species called Protarctos abstrusus, a close relative of modern bears. The bear is a little smaller than a black bear. This displays a flat head on a combination of characteristics of primitive and modern teeth, evidence of the transition position in evolutionary trees.
7. Gigantopithecus (Biggest Ape)
Gigantopithecus is the largest monkey ever found to date. Their height is estimated to reach around 3 meters. They are found in several regions in Asia, including China. Gigantopithecus lived at the end of the Tertiary period until the beginning of the Quaternary period. Gigantopithecus is an omnivore, eating bamboo and other plants.
Gigantopithecus was first discovered in 1935, when a German paleontologist discovered fossil teeth that were sold in Chinese drug stores. He knew that the tooth was from an unidentified primate. There is a theory that Gigantopithecus is still alive today. Some people believe that this animal is a yeti or snowman that is said to live in a Himalayan cave.
8. Quetzalcoatl (Largest Flying Animal)
Quetzalcoatlus is a Pterosaur, once the largest flying animal in history. The largest wingspan is 12 meters (as big as propeller-engined aircraft). Its life is approximately around the coast, because of the shape of its beak which makes it possible to catch fish.
9. Patagotitan mayorum
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 37 m (121 ft) with an approximate weight of 69 tonnes (76 tons).
10. Paus biru
Hewan terbesar yang pernah hidup di bumi adalah biru yang sampai sekarang masih berkeliaran di lautan. Paus ini panjangnya mencapai 33 meter dengan berat mencapai 150 ton.
Bayangkan jika kita dilahirkan di jaman sejak jutaan tahun lalu. Kita akan jadi bulan-bulanan para hewan-hewan raksasa di atas. Bersuyukurlah kita hidup di jaman sekarang ya gaess!
