A hailing land in a fossilized air giant has opened a window of a dramatic attack that was released millions of years ago.

The well-preserved pteranodon – a type of pterosaur that had a weapon developed – had the teeth embedded between the necked veins, giving clear evidence of shark bites.

These fossils offer a rare insight into an interplay of predators and prey that play in the ancient Oceans of North America.

Researchers came across the fossil in the collection of the Los Angeles County Natural History Museum, where it had been unstudiated since the 1960s.

Interested in shark teeth, they would first have to ensure that it had not only stopped fossilizing next to the pterosaur legs.

They concluded that it was embedded between the vertebra’s backs was evidence of a fast, violent piece of an 8ft shark like Cretoxyrhina mantelli .

This unique fossil reveals a long history of sharks attacking airborne animals that continue today with modern species of hunting birds.

“Understanding these ecologies is important to understanding life on earth through time,” says the senior professor professor Michael Habib, from the University of Southern California.

“We now know that sharks chased flying animals a long time ago as 80 billion in 19009026].

5/18 The discovery of a new type of dinosaur

Ledumahadi Mafube was about 200 million years ago in what now is South Africa. Recently discovered by a team of international researchers, it was the country’s largest land animal, weighed 12 tons and stood at 13 feet. In Sesotho, the South African language means in the region where the dinosaur is discovered, the name means “a giant dawn at dawn”

Researchers have witnessed a planet birth for the first time ever.
This spectacular image from the SPHERE instrument on ESO’s Very Large Telescope is the first clear picture of a planet captured in the very appearance of the formation around the dwarf star PDS 70. The planet is clear, visible as a bright spot to the right of the center of the image, which is blacked by coronagraph mask used to block the dazzling light of the central star.

Long thought to be dense connective tissue is actually a series of fluid-filled compartments that researchers have called ” interstitium “.
These compartments are beneath the skin, as well as the stomach, lungs, blood vessels and muscles and combine to form a network supported by a network of strong, flexible proteins.

By using sensitive analysis of the chemical composition of the sweat, researchers could tell the difference between those who had been directly exposed to heroin and cocaine, and those who had encountered it indirectly.

While researchers said they could not exclude spelling, the researchers said it was possible that the shark had picked the reptile from the sky or taken it after landing on the water.

Due to fossil evidence, paleontologists have been able to assume that the pterosaurs ate fish and could take off and land from water, although this would have left them vulnerable to attack.

“We know big sharks at the pterosaurs, so we could say that a great fast predator would have eaten this pteranodon when it got into the water, but we will never know exactly,” says Professor Habib.

The discovery was published in the journal PeerJ .
