Was there some catastrophic event? From Osborn (1932). Whenever I visit the American Museum of Natural History in New York I make sure to at least pass through the fourth-floor fossil halls before I leave, and one of my favorite displays features the shovel-mouthed proboscidean Platybelodon. From Osborn (1932). Platybelodon … An illustration of a complete Platybelodon skull. Synonyms: Amebelodon loomisi,‭ ‬Torynobelodon barnumbrowni,‭ ‬Torynobelodon loomisi. From Lambert (1992). Are you procrastinating more? Two valid species are currently placed within this genus, which was endemic to North America. ... - The gomphotheriid mammal Platybelodon from the Middle Miocene of Linxia Basin, Gansu, China. (The Platybelodon fossils were so common, in fact, that Osborn thought it to be diagnostic of the Tung Gur Formation in which it was found.) Has the state reconciled its racist past? It was added in Build 8.0.1, is the second member of the elephant order after the larger mammoth. Because of the resemblance of these lower tusks to shovels, Amebelodon is commonly referred to as a "shovel-tusked" gomphothere (another shovel-tusked gomph… [2][3][4] The species Amebelodon floridanus was relatively small, a little smaller than living elephants, and was common in fossil sites from 9 to 8 million years ago. From Osborn (1932). Looked at from the side the lower jaw also angled down to truly form a concave scoop that differed from the tooth-shovel seen in Amebelodon. Platybelodon ("flat-spear tusk") was a genus of large herbivorous mammal related to the elephant (order Proboscidea).It lived during the Miocene Epoch, about 15-4 million years ago, and ranged over Africa, Europe, Asia and North America. Based upon wear patterns on its teeth it seems like Amebelodon not only used its teeth/lower jaw to shovel, but also to scrape bark from trees and otherwise gather food from different sources. [4][6], Amebelodon was once thought to be widespread, but a study of Konobelodon in 2012 shortened the genus' range span, with the specimens found in China moved to the genus Protanancus. Was it a death assemblage caused by drought? Apabila diusut, ternyata Archaeobelodon merupakan moyang dari platybelodon… [4] One lineage of species once assigned to Amebelodon, including Amebelodon britti and North African Amebelodon cyrenaicus, is now placed in a separate genus called Konobelodon, formerly considered to be a subgenus. Platybelodon was very similar to Amebelodon, another closely related gomphothere genus. The lower jaw of a juvenile Platybelodon. A traditional restoration of Platybelodon as seen in H.F. Osborn’s 1936 elephant monograph. At first Osborn thought that Granger had discovered a new species of the “shovel tusked” proboscidean Amebeldon which had recently been found in Miocene-aged deposits Nebraska and described by E.H. Barbour. The shovel-tusker from Nebraska and the shovel-mouthed proboscidean from Mongolia were different, with Granger’s find more closely resembling Borissiak’s Platybelodon. 450 butterfly species rapidly declining due to warmer autumns in the western U.S. Tree of heaven is a hellish invasive species. Platybelodon ("flat-spear tusk") was a genus of large herbivorous mammals related to the elephant (order Proboscidea). In 1932 Henry Fairfield Osborn and Walter Granger published a paper entitled “Platybelodon grangeri, Three Growth Stages and a New Serridentine From Mongolia.Platybelodon grangeri, Three Growth Stages and a New Serridentine From Mongolia.” It would provide the basis for the current museum display, but its roots actually stretch back a few more years. Platybelodon (‘plat-ee-bell-oh-don’, meaning “Flat-Speared Tusk”) AKA the 'Shovel Face', is a medium-sized prehistoric ice age herbivore that resembles an odd looking elephant from African and Asian savannahs. [7], Lambert, W. D., 1990. This arrangement contrasted strongly with that of a juvenile specimen, which had a more strongly Y-shaped lower jaw, a more defined scoop, and large lower incisors. Rather than being a specialist its distinctive jaws and teeth allowed it to feed in a variety of ways on different plant foods. Rediagnosis of the genus, Lambert, W. D., 1996.

Osborn wrote; It seems probable that this bevel was produced by abrasion against a smooth rock or against the bottom of a shallow pond or stream in the process of scooping up vegetation, a process in which the broad short trunk was used in connection with the mandibular scoop. Lambert was not sure, but he proposed an interesting alternate explanation. Platybelodon was very similar to Amebelodon, another, closely related gomphothere genus. *, *[I assume that all the digging Granger and his crew did disturbed things quite a bit, but it would have been nice to have seen a taphonomic study done at each of the quarries. 10 curiosities of the elephant with a trunk that opened 1. In Tassy, P. and. Just because the lower-jaw of Platybelodon looked shovel-like does not mean it used it like a shovel. However, considerable evidence indicates that Amebelodon actually had a long, flexible trunk very much like that found in modern elephants, and that it probably was important for feeding, drinking, etc. Like it, platybelodon … Elephants similar to Amebelodon include Platybelodon and Gomphotherium amongst others. [4][6] Overall, the evidence indicates that this animal was a versatile browser (an animal that eats broad-leaved plants rather than grass), feeding in both wet and dry settings in a variety of ways. Adult Platybelodon grangeri had mouth scoops as wide as the back of the jaw, but the jaw pinched in strongly before the part of the jaw containing the premolars and molars. Like other typical gomphotheres, Amebelodon possessed two sets of tusks, one upper set, (much like those found on modern elephants), and one lower set that extended from the very front of the lower jaws. Rivers and lakes are the most degraded ecosystems in the world. If Platybelodon did engage in this feeding style it could account for the crescent-shaped indentations in its front, lower incisors as well as the sharpness of those teeth.

Platybelodon was related to Amebelodon and therefore it may have used its tusks in much of the same way. The shovel-tuskers include four generally recognized genera: Amebelodon, Platybelodon, Torynobelodon and Serbelodon although the latter has sometimes been united with Amebelodon (Tobien, 1972). Due to the shape of the two lower teeth, which are worn by many gomphothere genera (such as Platybelodon, Archaeobelodon, and Amebelodon… This appeared to be confirmed by the beveled edges on the lower incisors in the specimens Granger had collected.

The lower jaws of Amebelodon (bottom) and Platybelodon (top) compared. Ancestry travel on pause? In 1927 the Russian paleontologist A.A. Borissiak described the Miocene proboscidean Platybelodon from bones found in the North Caucasus region, but Granger’s fossils (found in 1928) came from Mongolia and were thought to represent a new species (Platybelodon grangeri). Due to the shape of the two lower teeth, which are worn by many gomphothere genera (such as Platybelodon, Archaeobelodon, and Amebelodon), they are popularly known as "shovel tuskers." Platybelodon was very similar to Amebelodon… Granger had hit the Platybelodon jackpot. Classification Platybelodon was an early mammal. How ‘dolphin safe’ is canned tuna, really? Amebelodon had a long, thin jaw with extended, scoop-shaped incisors. The most distinctive characteristics of this genus were its broad, scoop-shaped lower jaw and large, flat lower tusks (incisors). [5], Like other typical gomphotheres, Amebelodon possessed two sets of tusks, one upper set, (much like those found on modern elephants), and one lower set that extended from the very front of the lower jaws. Platybelodon was an ancestor of the modern elephant that looked like it got hit in the face with a shovel, then absorbed that shovel into its mouth. Due to the shape of the two lower teeth, which are worn by many gomphothere genera (such as Platybelodon, … Did each bonebed represent an accumulation over a long period of time? Paleobiology 18 (2): 132-147. https://en.wikipedia.org/w/index.php?title=Amebelodon&oldid=1005217585, Creative Commons Attribution-ShareAlike License, This page was last edited on 6 February 2021, at 15:44. Platybelodon was very similar to Amebelodon, another, closely related gomphothere genus. Amebelodon berasal dari genus proboscidean. However, as mentioned above, the lower tusks of the Amebelodon were distinctive in that they were relatively long, slender, and flattened. Platybelodon ("flat-spear tusk") was a genus of large herbivorous mammal related to the elephant. Other species once assigned to Amebelodon are now assigned to the genus Konobelodon, which was once a subgenus. Kesamaannya adalah gigi bawah yang mirip dengan sekop. Gigi bawah yang rata ini terbentuk akibat kebiasaannya memakan vegetasi yang keras. From Osborn (1931). What was the function of such an arrangement? The main and most curious feature of platybelodon is its trunk, which it opened and in which he had two big teeth .It is … The youngest record of Amebelodon is from a 5-million-year-old site in North America. From Lambert (1992). Konidaris, G. E., S. J. Roussiakis, G. E. Theodorou, and G. D. Koufos. It presents taxonomic, distributional, and ecological data about the entire fossil record. The distal end of the lower jaw of an adult Platybelodon. Description Edit. Lambert hypothesized that Platybelodon used its unique lower jaw as a scythe, plucking up vegetation with its trunk and then rubbing it against its teeth to saw through it. They probably could have, but it does not appear that they did so with any regularity. Amebelodon britti had very large upper and lower tusks; the lower tusks about 4 feet long, and the upper tusks about 4.5 feet long. Either way, it seems that Platybelodon or Amebelodon were not the sifters of swamp-muck they have traditionally been portrayed as. After you get a COVID-19 vaccine, what can you do safely?

Paleontologists have theorized it would’ve used its tusks as a shovel to dig up and … Could a fungus save the day? Other larger but somewhat younger common North American species include Amebelodon fricki. If stood up on the front incisors the lower jaws of an adult Platybelodon grangeri would have looked like a shovel with two toothy handles. Although it thrived during its time, it did not survive past the Miocene. The lower jaw of a fetal (?) Platybelodon. Because of the resemblance of these lower tusks to shovels, Amebelodon is commonly referred to as a "shovel-tusked" gomphothere (another shovel-tusked gomphothere that may or may not be closely related to Amebelodon is Platybelodon). It lived during the late Miocene epoch in Asia and the Caucasus. The specimen identified as belonging to a fetus was relatively short with no real “scoop” at the front of the lower jaw (even if the sides of the lower jaw did “pinch in” a little to indicate where this scoop would eventually develop).

Neither did Platybelodon use its shovel-shaped jaws in the way Osborn envisioned. [1], Amebelodon first appeared in the Great Plains and Gulf Coast regions of North America during the late Miocene, roughly 9 million years ago, and apparently became extinct on this continent sometime around 6 million years ago. Lambert’s hypothesis was developed after others had failed and perhaps there is some alternate explanation that might also be consistent with the fossil evidence. Platybelodon, by contrast, had a shorter but broader jaw with short, square incisors. In a glass case in the shadow of a mammoth skeleton is a growth series showing the development of the Platybelodon jaw, from juvenile to adult. Platybelodon … The biogeography of the Gomphotheriidae of North America. Neither does Lambert’s plant-processing hypothesis close the book on how Platybelodon used its lower jaws. However, an analysis of wear patterns has shown that these lower tusks were most likely used in a variety of ways in addition to shoveling, including scraping bark from trees. By 1931 at the latest, however, Osborn changed his mind. However, wear patterns on the teeth suggest that it used its lower tusks to strip bark from trees. This deep-sea shark is one of the world’s largest glowing animals. I do not know.].

Like many AMNH displays, however, this series was not a product of the renovation of the fossil halls in the 1990’s but came out of much earlier research. Quarry 1 yielded at least 16 individuals, most of which were adults, and Quarry 2 contained one adult, about eight juveniles, and one specimen found between the hips of an adult that Osborn considered a fetal Platybelodon. Amebelodon had a long, thin jaw with extended, scoop-shaped incisors. Sentenced to death, but innocent: These are stories of justice gone wrong.
