The body length of Livyatan is unknown since only the holotype skull is preserved. Lambert and colleagues estimated the body length of Livyatan using Zygophyseter and modern sperm whales as a guide. The authors opted to use the relationship between the bizygomatic width (distance between the opposite zygomatic processes) of the skull and body length because of the variable rostrum length in modern sperm whales and the rostrum of Livyatan being proportionally shorter. Doing so produced length estimates of 13.5 m (44 ft) when using the modern sperm whale and 16.2–17.5 m (53–57 ft) when using Zygophyseter.[1][17] It has been estimated to weigh 57 tonnes (62.8 short tons) based on the length estimate of 17.5 m (57 ft).[18] By comparison, the modern sperm whale length measures on average 11 m (36 ft) for females and 16 m (52 ft) for males, with some males reaching up to 20.7 m (68 ft) long.[20][21][22] The large size was probably an anti-predator adaptation, and allowed it to feed on larger prey. Livyatan is the largest fossil sperm whale discovered, and was also one of the biggest-known predators, having the largest bite of any tetrapod. Diagram comparing the upper and lower size estimates of Livyatan (bottom three) with the size of mature sperm whales, including one of the largest individuals recorded (top three), and a human. Skull The holotype skull of Livyatan was about 3 m (9.8 ft) long. Like other raptorial sperm whales, Livyatan had a wide gap in between the temporal fossae on the sides of the skull and the zygomatic processes on the front of the skull, indicating a large space for holding strong temporal muscles, which are the most powerful muscles between the skull and the jaw. The snout was robust, thick, and relatively short, which allowed it to clamp down harder and better handle struggling prey. The left and right premaxillae on the snout probably did not intersect at the tip of the snout, though the premaxillae took up most of the front end of the snout. Unlike in the modern sperm whale, the premaxillae reached the sides of the snout. The upper jaw was thick, especially midway through the snout. The snout was asymmetrical, with the right maxilla in the upper jaw becoming slightly convex towards the back of the snout, and the left maxilla becoming slightly concave towards the back of the snout. The vomer reached the tip of the snout, and was slightly concave, decreasing in thickness from the back to the front. A sudden thickening in the middle-left side of the vomer may indicate the location of the nose plug muscles. Each mandible in the lower jaw was higher than it was wide, with a larger gap in between the two than in the modern sperm whale. The mandibular symphysis which connects the two halves of the mandibles in the middle of the lower jaw was unfused. The condyloid process, which connects the lower jaw to the skull, was located near the bottom of the mandible like other sperm whales. Teeth The teeth of Livyatan were among the biggest of any animal at over 31 cm (12 in) in length Unlike the modern sperm whale, Livyatan had functional teeth in both jaws. The wearing on the teeth indicates that the teeth sheared past each other while biting down, meaning it could bite off large portions of flesh from its prey. Also, the teeth were deeply embedded into the gums and could interlock, which were adaptations to holding struggling prey. None of the teeth of the holotype were complete, and none of the back teeth were well-preserved. The lower jaw contained 22 teeth, and the upper jaw contained 18 teeth. Unlike other sperm whales with functional teeth in the upper jaw, none of the tooth roots were entirely present in the premaxilla portion of the snout, being at least partially in the maxilla. Consequently, its tooth count was lower than those sperm whales, and, aside from the modern dwarf (Kogia sima) and pygmy (K. breviceps) sperm whales, it had the lowest tooth count in the lower jaw of any sperm whale. The most robust teeth in Livyatan were the fourth, fifth, and sixth teeth in each side of the jaw. The well-preserved teeth all had a height greater than 31 cm (1 ft), and the largest teeth of the holotype were the second and third on the left lower jaw, which were calculated to be around 36.2 cm (1.2 ft) high. The first right tooth was the smallest at around 31.5 cm (1 ft). The Beaumaris sperm whale tooth measured around 30 cm (1 ft) in length, and is the largest fossil tooth discovered in Australia. These teeth are thought to be among the largest of any known animal, excluding tusks.[1][8] Some of the lower teeth have been shown to contain a facet for when the jaws close, which may have been used to properly fit the largest teeth inside the jaw. In the front teeth, the tooth diameter decreased towards the base. This was the opposite for the back teeth, and the biggest diameters for these teeth were around 11.1 cm (4.4 in) in the lower jaw. All teeth featured a rapid shortening of the diameter towards the tip of the tooth, which were probably in part due to wearing throughout their lifetimes. The curvature of the teeth decreased from front to back, and the lower teeth were more curved at the tips than the upper teeth. The front teeth projected forward at a 45° angle, and, as in other sperm whales, cementum was probably added onto the teeth throughout the animal's lifetime. Reconstructed skull at Natuurhistorisch Museum Rotterdam All tooth sockets were cylindrical and single-rooted. The tooth sockets increased in size from the first to the fourth and then decreased, the fourth being the largest at around 197 mm (7.8 in) in diameter in the upper jaws, which is the largest of any known whale species. The tooth sockets were smaller in the lower jaw than they were in the upper jaw, and they were circular in shape, except for the front sockets which were more ovular. Habilities - Primary attack. A strong bite. - Secondary attack. A sonar which could detect dinos in the same way as the bloodstalker. Only for 4 seconds and with a cooldown of 60 seconds - Tertiary attack. A dash with which it could grab his prey with it's mouth to bite it so hardly, harder than the primary attack. It could onli go fordward without moving during the animation. It will have a cooldown of 10 seconds. Disadvantages - Necessity to breath after 30 minutes with oxigen because it will drown if it doesn't breath. - The same as the Basilosaurus. If it goes so deep it will start getting damage.

Edmontosaurus

The Diprotodon is a Pleistocene marsupial from Australia. The Diprotodon could be found all over any map, but they prefer swamps and desert oasis habitats. The Diprotodon can be used as an all terrain pack animal. Gaining a hydration bonus to help defend it while traversing the landscapes of the ARKs, and has a very hefty saddle unlocked at around lvl. 40. It also has weight reduction on most raw materials including fibre, thatch, wood, and stone, with considerable weight to boot. It has a bite attack that can harvest berries, thatch and seeds. It also has a stomp that can harvest fibre and wood, and does knock-back to creatures smaller than a Baryonyx. The saddle can carry two people, plus has additional pockets for shoulder pets, and the ability to whistle them from the saddle allowing for easy transport. The Diprotodon also has a an immunity to swamp fever and leech damage, but the ability to auto pick off leeches, while getting leech blood in return, making it an efficient way to obtain the blood. All in all, the Diprotodon is probably the all terrain pack tame that can see through many tough travels across the ARK. https://en.wikipedia.org/wiki/Diprotodon

The Asphalt Venator was a formidable and very cunning hunter Advantages: It has a reduction to the damage of small creatures such as sabertooths, wolves or raptors. At the same time, its skin allows it to live both in places like the mountains near the voocans where there are high temperatures and in the desert. It is easy to use once tamed, its great speed and sense of smell allow it to find prey easily Skills: Once mounted, the asphaltvenator can indicate where other creatures and players are located, like the ability of the parasaur but this time in a very aggressive carnivore. It has a death that generates tears like ravagers or allosaurus and a roar that intimidates creatures like that of the rex It is an excellent cargo dinosaur, it can carry large amounts of materials. Although it is known that asphaltvenators are solitary dinosaurs, females become much more aggressive and strong once they have their first young, they have a higher life and damage bonus than a male

Diprotodon is the largest known marsupial to have ever lived. It grew as large as 1.8 m (5 ft 11 in) at the shoulders, over 4 m from head to tail, and possibly almost 3,500 kg in weight. It supported itself on elephant-like legs to traverse long distances, and was able to colonise most of Australia. The digits were weak, and most of the weight was probably borne on the wrists and ankles. This would (in ark fashion) be upscaled to become even bigger than many large creatures. Although Diprotodon looks like a megatherium, it would not be as strong of an attacker, but it would have an incredible weight, stamina, harvest amount, and of course tons of health. It would be a great choice for a late game harvester, specialising in berries and wood, where it uses its buck-teeth. As a reference to its ancient herd nature, it would spawn in groups of 3-5, and would attack players who tried to fight their friends. But if they were found alone, Diproton would run away, at a speed fast for its size. They would be found in plains, and sometimes in deserts. Diprotodon - Wikipedia

Species : Edmontosaurus Regulis Common name : Edmontosaurus Time : Upper cretaceous Diet : Herbivore Temperament : Aggressive Wild : Edmontosaurus is an ancient hadrosaurus, but this one is anything but harmless. It's rumored that this dinosaure caused the death of way too many survivor who commited the mistake of underestimate them. Their innate ability to spit an acidic saliva that can melt trought any armor with ease is already enought to scare even the most seasoned survivors, but add his powerfull hooves and your in for a very bad day, if you came unprepared. Domesticated : Edmontosaurus Regulis will not tolerate the presence of survivor near him, but when tamed they can lead you to even the most dangerous place of the Arks. Edmontosaurus Acidic Ability (Cool down: 15 second): The Edmontosaurus ability to spit acid as nothing to do with the arthropleura similar hability. The edmontosaurus spit is more likely to be associated to vomit then anything else. As a matter of fact, when your hit by it's stiky and slimy salive, it thend to cover you entirely reducing your amor ressitance quickly to nothing. Once it has dissolved your armor it's impact on your skin is similar to the dammages sustained when you stand too close to a reaper's body. Taming method : To tame one of these beast, you will need a shield and some rareshroom, you will need to get hes agro, and pull out your shield until he launch his spiting attack, when he does it, feed it passively your rare mushrooms, after repeat the process until his tamed. Which should take a while. Base stats : Edmontosaurus have a great ammount of health and can deal a reasonable ammount of damage. They are not the quickest land animals but their near semi-aquatique nature provide them with a descent swimming speed, however it's inability to breath underwater prevent him from diving for too long. PVP uses : Like the Arthropleura the Edmontosaurus spits deals lot of dammage to metal and tek structures. Which help you to raid other survivor bases, while also being able to defeat the creatures of the other tribes. Conclusion : Edmontosaurus would be a end game dinosaurs, being able to defeat strong creature and raid well protected base. So if you'd like Edmontosaurus to be in the game uppvote this dino so others players can see this Strong Hadrosaurs as the game lacks of Hadrosaur and strong herbivore.
