Thalassocnus és un gènere extint de peresós marí aquàtic o semiaquàtic que visqué a Sud-amèrica durant el Miocè i el Pliocè. [11] Upon species description in 1995, they were moved into the subfamily Nothrotheriinae. Over time, they apparently shifted from a preference for feeding in shallow water to a preference for deeper waters. They have been found in the Pisco Formation of Peru and the Bahía Inglesa, Coquimbo, and Horcón formations of Chile. Thalassocnus were ground sloths that lived from the Late Miocene to the end of the Pliocene—Late Huayquerian to Early Uquian in the SALMA classification—and all five species were discovered in different horizons of the Pisco Formation in Peru. Conversely, the later species, T. carolomartini and T. yaucensis, lacking these marks, probably fed in deeper waters in a manner similar to manatees. You like to control everyone within your influence, to shape things to your own liking. They were probably preyed upon by sharks and macroraptorial sperm whales such as Acrophyseter. 5. thalassology : German - English translations and synonyms (BEOLINGUS Online dictionary, TU Chemnitz) Early Thalassocnus were probably generalist grazers eating seaweed and seagrasses close to shore, whereas later species specialized on seagrasses farther off the coast. [21][22] Other vertebrates include the seals Acrophoca and Hadrokirus, sea turtles such as Pacifichelys urbinai, the crocodile Piscogavialis, cormorants, petrels, and boobies (Sula spp.). The pterygoid muscle in later species was larger to adapt to a grinding motion rather than a cutting motion while chewing. [13], The later Thalassocnus species had enlarged premaxillae and thus had a more elongated snout. They probably fed on Zosteraceae seagrasses, which are known from the Pisco Formation, specifically the marine eelgrass Zostera tasmanica, which is now only known from Australia. Anar'alah= By the light. Based on a femur-to-body-length ratio, the T. littoralis specimen—probably a female—measured 2.1 meters (6.9 ft) in life, and the T. yuacensis specimen 3.3 meters (11 ft). Thalasso- definition, a combining form meaning “sea,” used in the formation of compound words: thalassocracy. They may have also used the claws to grab onto rocks during strong waves, and there are tibiae and fibulae remains that have been broken and healed, indicating the individual may have been thrown against the rocks of the shore during a storm. Al diel shala= Safe travels. Information and translations of Thalasseus in the most comprehensive dictionary definitions resource on the web. Thalassian definition: a sea turtle | Meaning, pronunciation, translations and examples Thalassocnus were found in formations with large marine mammal and shark assemblages. Pronunciation of Thalassocnus found 3 audio voices for Thalassocnus. Anar'alah belore= By the light of the sun. However, these adaptations also developed in some terrestrial mammals, and so could instead be related to chewing efficiency. [15] Thus, Thalassocnus would have been poorly adapted to the changing conditions even if enough seagrass remained to subsist on. This also increased the size of the mouth. [4] In 2017, the sloths were moved back to the family Megatheriidae. Thalamus Name Meaning. Thalassis name numerology is 9 and here you can learn how to pronounce Thalassis, Thalassis origin and similar names to Thalassis name. antiquus, T. natans, T. littoralis, T. carolomartini, and T. yuacensis—represent a chronospecies, a population gradually adapting to marine life in one direct lineage. From Θαδδαῖος (Thaddaios), the Greek form of the Aramaic name Thaddai.It is possibly derived from a word meaning "heart", but it may in fact be an Aramaic form of a Greek name such as Θεόδωρος (see THEODORE).In the Gospel of Matthew, Thaddaeus is listed as one of the twelve apostles, though elsewhere in the New Testament his name is omitted and Jude's appears instead. Thalassinos Expression, Thalassinos Soul Urge, Thalassinos Inner Dream. [21][23], In Chile, the Bahía Inglesa Formation in the Caldera Basin is known for a large shark population, especially the broad-toothed mako and the great white shark (Carcharodon carcharias). T. antiquus probably did not enter the water to feed, instead eating plants that washed ashore. Anaria shola= Speak your business. It is monotypic within the subfamily Thalassocninae. There is nothing surprising in this: both names have the … Unlike other ground sloths which put a lot of stress on their hind limbs for locomotion—specifically from standing on two legs (bipedalism)—the leg bones of Thalassocnus are slender. What does Thalasso mean? Most of the bony fish findings represent tunas and croakers. Thalassocnus is an extinct genus of apparently semiaquatic (for the geologically oldest species) or fully aquatic (for the geologically most recent species) marine sloth from the Miocene and Pliocene of South America. The long tail was probably used for diving and balance similarly to the modern day beaver (Castor spp.) [4] Specimens were also found in the Bahía Inglesa Formation,[5] the Coquimbo Formation, and the Horcón Formation in Chile. Thalassocnus is an extinct genus of semiaquatic ground sloths from the Miocene and Pliocene of the Pacific South American coast. [9] T. carolomartini from a skull, SMNK PAL 3814, and hands, SMNK PAL 3814, was also described in 2002, and the two T. carolomartini specimens may represent one individual. Anar'endal dracon= By the breath of the dragon. The five species—T. [13][8][15][17] The legs also became more flexible, with later species able to, at maximum extension, have the femora reach a horizontal position parallel to the torso. The digits decreased in size in later species. [14] Thalassocnus, as time progressed, increased in size. The English for θάλασσα is sea. Thalassocnus is an extinct genus of semiaquatic ground sloths from the Miocene and Pliocene of the Pacific South American coast. [5][24] Pachyptila prion seabirds were found here. [15], Indicated by the large fossae, or depressions, on the shoulder blades, elbow, and wrist, the later Thalassocnus species had strong arm muscles. It is possible the name you are searching has less than five occurrences per year. They are the only known aquatic sloths. Thalassocnus (tunnetaan myös nimellä vesilaiskiaiset) on sukupuuttoon kuollut erikoistuneiden maalaiskiaisten suku.Se kuului heimoon Nothrotheriidae ja oli läheistä sukua heimon Megatheriidae jättimäisille maalaiskiaisille. [2] However, a 2018 analysis retains Thalassocninae within Nothrotheriidae. They were apparently grazers of sea grass and seaweed. [13][15], The later species fed entirely on the seafloor, similar to sirenians (manatees and dugongs) and the extinct desmostylians, becoming specialist bottom feeders of seagrasses. Aparentment pasturava herba marina i algues. Thalassius name meaning available! The femur and kneecap are smaller in T. yuacensis than in T. natans. T. antiquus had a bone density comparable to terrestrial ground sloths. It is monotypic within the subfamily Thalassocninae. [17], The earlier species, like other sloths, bore their weight on the sides of their feet (pedolateral), whereas the later species planted their feet flat (plantigrade) to better paddle and walk along the seafloor. 9. Hoorah! Thalassocnuksen eläessä sisämaa oli karua aavikkoa, joten se joutui sopeutumaan hankkimaan ravintonsa merestä. 2. The later species had a more powerful bite to better grasp seagrass. [8] T. littoralis was described from a nearly complete skull, MUSM SAS 1615, in 2002. The earlier species had more rectangular teeth that had a similar build to the giant ground sloth Megatherium americanum, whereas the later species had squarer and larger teeth.

This individual may have used its claws to drag itself onto shore. [13][15], Thalassocnus may have competed with dugongine sirenians for seagrasses, although the latter were apparently rare in the area. Fossils found to date have been from the coast of Peru. : They were apparently grazers of sea grass and seaweed. The skulls show disparity in general size, slenderness of teeth, and the length of the premaxillae—which make up the snout. This inclination may have caused less-developed back muscles that would have been needed for high-powered swimming. Add Image Thalassocnus is an extinct genus of apparently semiaquatic (for the geologically oldest species) or fully aquatic (for the geologically most recent species) marine sloth from the Miocene and Pliocene of South America. and platypus (Ornithorhynchus anatinus), which use their tails for balance and diving rather than propulsion while swimming.

See more » Armadillo. The teeth were prism-shaped with a circular cross section, and the teeth interlocked tightly while chewing in the later species. [13], Thalassocnus fossils have been found in Peru and Chile, an area which has been a desert since the Middle Miocene. which use their long tails to provide downward lift to resist buoyancy. In earlier species, the chewing pattern sharpened their teeth. In 1968, taxonomist Robert Hoffstetter placed undescribed sloth remains into the family Megatheriidae, possibly belonging to the now-defunct subfamily Planopsinae, mainly based on similarities with the ankle bone and femur. This feeding style probably involved bottom-walking, like hippopotamuses and the extinct desmostylians, and digging. Dinosaur Wiki is a FANDOM Lifestyle Community. The size difference in the premaxillae are reminiscent of the developed upper lips or proboscis in males of modern mammals like the elephant seal (Mirounga spp.). Historically, surnames evolved as a way to sort people into groups - by occupation, place of origin, clan affiliation, patronage, parentage, adoption, and even physical characteristics (like red hair).

Se n'han trobat fòssils a la costa del Perú. Thalassocnus probably walked across the seafloor and dug up food with its claws. The third digit was constantly flexed, perhaps acting like a crampon to anchor itself to the seafloor while digging. They possessed no adaptations for high-powered swimming, probably paddling like terrestrial mammals. The formation has a large cartilaginous fish assemblage, mainly belonging to the ground sharks, such as requiem sharks and hammerhead sharks; and, to a lesser extent, mackerel sharks, such as white sharks, sand sharks, and Otodontidae.
