What did the largest marine animal, the New Zealand ichthyosaur, eat and grow up?

Living in the Triassic dinosaur era, New Zealand's great ichthyosaur has surpassed the blue whale, the largest modern marine animal, and is considered the largest animal in the ocean that humans have discovered so far. New Zealand's great ichthyosaurs are also divided into different species, the longer ones can reach more than 38 meters, and the larger ones can reach about 406 tons, and their favorite sea creatures are squid, as well as small fish and shrimp in the ocean, and the diet is similar to that of today's whales.

The skeleton of the New Zealand Ichthyosaurus was discovered by a paleontologist on the banks of the Marlborough River in New Zealand in 1978. Scientists found according to the restoration of its skeleton fossils that the head of this big fish dragon is somewhat like a dolphin, with a long and pointed mouth with cone-shaped serrations, some like the mouth of a swordfish, and scientists have also found that its eyes are very large, with a diameter of 20 to 30 centimeters, and now the eyes of the largest marine animal, the blue whale, are only 15 centimeters wide, which shows that in the ocean at that time, the eyesight of the New Zealand big ichthyosaurus must be very good, because the big eyes are easier to absorb light, and the eyesight must be good. It can ensure that the big ichthyosaur can catch food in the dimly lit depths of the ocean or at night.

According to the analysis of the substance of the stomach of the fossil skeleton of the big ichthyosaur, scientists believe that this is part of the tentacles of a squid, combined with the analysis of modern marine zoological knowledge, it is believed that the eating habits of the big ichthyosaur in New Zealand at that time are similar to those of the current whales, mainly to prey on the squid marine creatures for food, in addition to small fish and shrimp are not less.

HabitsNew Zealand Ichthyosaurus resembles a dolphin in appearance, with a streamlined body, which is very suitable for swimming and living in the water. According to scientists' estimates, the speed of the big ichthyosaur is very fast, it can reach a speed of about 40 kilometers per hour, and the depth of the dive can reach 500 meters, so the sea adaptability has been able to catch a wide range of marine animals for food, so the New Zealand big ichthyosaur can grow to such a large size. In addition, the ancestors of the big ichthyosaur are actually reptiles on land, and they also reproduce in the form of laying eggs, but I don't know if the ichthyosaur will crawl to the shore to lay eggs after evolving to adapt to marine life.

New Zealand's big ichthyosaurs mainly eat sea creatures and small fish and shrimp to grow up slowly, but when they encounter a relatively large amount of heavy rain, they will also attack, and then they can also eat.

New Zealand ichthyosaurs lived in the age of dinosaurs during the Triassic period. It has surpassed the blue whale, the largest marine animal of modern times and arguably the largest animal in the ocean that humans have discovered so far. New Zealand ichthyosaurs are also divided into different types.

The longer ones can reach more than 38 meters, and the larger ones can reach 406 tons. Their favorite sea creatures are squid, as well as small fish and shrimp in the ocean. The recipe is similar to that of the current whales.

Ichthyosaurs may be physiologically different from baleen whales, and from an evolutionary convergence point of view, their feeding habits should be closer to those of toothed whales or dolphins, such as sperm whales or long-snouted dolphins. Most ichthyosaurs have tiny dolphin-like teeth, making them ideal for catching mollusks and fish, especially those like squid or octopus.

The New Zealand Great Ichthyosaur lived in the Triassic period, was 38 meters long and weighed tons. In 1878, paleontologists discovered the fossilized skeleton of an extinct large marine reptile that lived during the age of dinosaurs, an ichthyosaur with a dolphin-like head and a long, toothed snout, near the banks of the Marlborough River in New Zealand.

The ichthyosaur had a long, pointed mouth, tapered teeth in the upper and lower jaws, and the entire skull looked like a triangle. Like today's tuna, its body shape is suitable for fast swimming, the vertebral body is like a saucer, the sides are slightly concave, a vertebrae are like a string of saucers strung on a rope, and the tail vertebrae are narrow and flattened.

Some ichthyosaurs appear to be suitable for deep diving, with a pair of large, round eyes on either side of their heads, which can reach up to 30 centimeters in diameter, while the largest known living vertebrate eye is the blue whale's eye, which is only 15 centimeters in diameter. Ichthyosaurs can hunt down prey such as squid and fish at night or in the deep sea in dim light.

Scientists have calculated that according to several known ichthyosaurs of the same species, if the great ichthyosaur in New Zealand is a Saste ichthyosaur, it is considered like this according to the largest Sikani Sastet: body length and weight ton. If the New Zealand ichthyosaur is a Taymanan ichthyosaur, if the New Zealand ichthyosaur with the vertebrae is a Taymanan ichthyosaur, it is calculated according to the dorsal vertebrae

m, t; According to the base of the tail, it is meters, tons. If the New Zealand ichthyosaur is a genus of Ichthyosaurus, the New Zealand ichthyosaur in the shape of a Ichthyosaurus is 34 meters long and weighs a terrible ton.

The world's largest known blue whale is no more than 33 meters long and weighs only 181 tons. So it is likely that the New Zealand ichthyosaur belongs to the genus Sastertasaurus, and it will undoubtedly surpass the blue whale to become the largest known animal in size.
