Researchers examining a nearly complete skeleton of a 240-million-year-old “megapredator” have found another large reptile in its stomach.

According to a study published in the scientific journal iScience, the 15-feet long ichthyosaur known as Guizhouichthyosaurus had swallowed a nearly 12-foot long thalattosaurs.

“We have never found articulated remains of a large reptile in the stomach of gigantic predators from the age of dinosaurs, such as marine reptiles and dinosaurs,” University of California Davis professor and study co-author Ryosuke Motani said in a statement. “We always guessed from tooth shape and jaw design that these predators must have fed on large prey, but now we have direct evidence that they did.”

Ichthyosaur means “fish lizard,” an apt way to describe the giant sea-dwelling creature. The earliest known ichthyosaurs had long, flexible bodies and likely swam similar to modern-day eels, according to an article from the University of California Berkeley.

Given the size of the prey, it’s possible the ichthyosaur could be reclassified as an “apex predator,” putting it at the top of the food chain during the early part of the Mesozoic Era.

“Air-breathing marine predators have been essential components of the marine ecosystem since the Triassic,” the researchers wrote in the study’s summary. “Many of them are considered the apex predators but without direct evidence—dietary inferences are usually based on circumstantial evidence, such as tooth shape. Here we report a fossil that likely represents the oldest evidence for predation on megafauna, i.e., animals equal to or larger than humans, by marine tetrapods—a thalattosaur (∼4 m in total length) in the stomach of a Middle Triassic ichthyosaur (∼5 m).”

The researchers continued: “The predator has grasping teeth yet swallowed the body trunk of the prey in one to several pieces. There were many more Mesozoic marine reptiles with similar grasping teeth, so megafaunal predation was likely more widespread than presently conceived.”

Some ichthyosaur fossils discovered have shown the creatures to give birth to live, developed young. Unlike dinosaurs, which ichthyosaurs have been confused with, they did not lay eggs.

Megapredator, It’s still unclear which group of modern-day vertebrates are the closest relative to ichthyosaurs, but researchers have suggested they may have been an offshoot of diapsids, which includes dinosaurs, birds and pterosaurs. Others have suggested that it may actually be a distant relative of sea turtles.

Megapredator, A number of ichthyosaurs fossils have been discovered recently. In April 2018, the massive jawbone of a 205-million-year-old ichthyosaur was discovered in southwestern England, making it “one of the largest animals to ever live.” The fossils of a 180-million-year-old ichthyosaur, which also contained evidence of blubber and skin, were discovered in December 2018.

In January 2019, researchers used 3-D technology to unlock the secrets of a nearly 200-million-year-old ichthyosaur skull, which was discovered in a U.K. farmer’s field in 1955.

In December, a British man walking his two dogs on a beach in England stumbled upon what is believed to be the fossilized remains of a 65-million-year-old ichthyosaur.

Science & technology sector remain neglected in Pakistan; both at government and public level. Even, when it comes to development or criticism, there was no media to address the issues. We all know that the news media plays a critical role as one of the primary means through which scientific and technological issues are brought to the attention of the general public. The reality of science for most people is what they experience through mass media channels. Good reporting allows people to evaluate science policy issues and make rational personal choices; poor reporting can mislead a public that is increasingly affected by science. The need for the science and technology newspaper took place and the concept of weekly (future’s daily) newspaper “Technology Times” evolve.
