The 3.3-foot-long Eurypterid roamed the current Chinese waters about 435 million years ago, using its giant thorny arms to catch its prey.

Its thorny limbs “probably used to capture prey, and among arachnids … can draw similarities to the” catch basket “formed by the thorny pedipals of the tailless whip. “The co-author of the study, Bo Wang of the Nanjing Geological Institute, the Center for Paleontology, Life and Paleontology Excellence at the Chinese Academy of Sciences, and colleagues wrote in a new study. The pedipalp is the foremost appendage of arachnids. Normally, the focus is on transferring sperm from male spiders to female arachnids, but in some arachnids, such as the tailless whip, the pedipals are designed to prey.

Eurypterids come in a variety of sizes, the smallest being about the size of a human hand and the largest being about the size of an adult human. Live science previously reported.. Newly listed species, T. Researchers say xiushanensis was discovered to belong to the Mixopteriade family for the first time in 80 years.
“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 “.
T. xiushanensis It is also the first mixtopterid found in the supercontinent of GondwanaFormed after the larger supercontinent Pangea It split in two.
“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 wrote in a study. There is. “Future studies, especially in Asia, may reveal a more international distribution of Eurypterids and perhaps other groups of Eurypterids.”
