Prehistoric fossils of Eurypterid, about the size of a dog, were discovered in the early Silurian period in southern China, and the first large Eurypterid in this region of the world.
Fossils belong to Terropterus xiushanensis gen. etsp. A new species that is a member of Mixopterids is a group of Eurypterids that feature special arms lined with a special tooth-like structure used to catch prey with a kind of basket catch when stalking the ocean floor.
“Our knowledge of mixed wing is limited to four species in two genera,” said Professor Wang Bo of the Nanjing Institute of Geological Paleontology, Chinese Academy of Sciences. statement, “These were all based on some fossil specimens from the Silurian Lauru Russia 80 years ago.”
Discoveries reported in Scientific informationExpands our understanding of the distribution of such megafauna around the world and their incredible biodiversity.
T. xiushanensis It was described as 1 meter long, with a particularly enlarged prosome limb featuring a unique arrangement of spines. It stalked the pristine supercontinental shallows of the Gondwana continent, which was one of two parts of Pangea’s ancient peculiar land mass after it collapsed. It is believed to have lived between 443.8 million and 419.2 million years ago.
“Our knowledge of these strange animals is limited to four species of two genera described 80 years ago: Mixopterus kiaeri in Norway, Mixopterus multispinosus in New York, Mixopterus simonsoni in Estonia, Scotland. Lanarkopterus dorichoschelus, “the researchers wrote in the study.
“Our first Gondwana mixed wing, along with other Eurypterids from China and some undescribed specimens, suggests a prejudice against undercollection in this group,” the researchers added. “Future studies, especially in Asia, may reveal a more international distribution of Eurypterids and perhaps other groups of Eurypterids.”
Analysis: Megafauna wasn’t just dinosaurs and mammoths
When it comes to prehistoric Megafauna, the incredible variety of species is truly amazing.
Dog-sized scorpions are arguably an eye-catching discovery in fossil records, but when you walk to Earth or roam the ocean today, there are all sorts of ridiculously large creatures that look like something in a horror movie.
This is noteworthy in many respects, as evolution usually seeks to reduce the physical weight of a species as much as possible. The bigger something is, the more energy and work the body has to exert to maintain itself.
It is still controversial why nature allows such giant creatures, but it is believed that such creatures have developed. During the colder and more ice age As the Earth’s climate warmed over time, it slowly began to decline. This is probably a good thing, as few people are alive.
