The picture shows the Canadian ditch scale fish, which belongs to the same carcass order of the shield fish as the tyrannosaur ditch scale fish
A multi-institutional research team discovered the newest and largest member of the order Carotidium. Carapaceae are extinct beetlefish.
The newly discovered fish, called the Doubleriolepis rex, dates back to the Devonian Period, about 370 million years ago, and was floating in the water long before dinosaurs took to the stage of history. The bone plate covers its front fin, shoulders and head, and is about 1.65 meters long, making it the largest newly discovered carcass turtle, about 30% longer than the Giant Groove Scale Fish (Bothriolepis maxima).
Researchers from Drexel University, Delaware Valley University, Stanford University, and the University of Chicago made the discovery together, publishing their findings in the journal Vertebrate Paleontology.
Fossils of the Bawanggou scaly fish have been found on Ellesmere Island in The Nunavut region of Canada, including a thick bone plate covering the head of this ancient creature. The researchers say that the bulbophyllum may use bone plates to fend off attacks from large predatory fish.
The Overlord Ditch Scaled Fish is not violent.
Despite the name "overbearing", it is not a ferocious predator. Scientists say the Tyrannosaurus, like other compatriots in the family Crateridae, is an underwater fish, cruising on the sandy seabed and feeding on dead plants and animals.
The study's lead author, Jason Downs of the University of Delaware Valley, said in a statement that the flattened abdomen and the downward-facing mouth of the bulbophyllum "are not physical characteristics of predators."
The picture shows a top-down sketch of the bones and head of the skull of the bulbophyllum. There are eye openings on the bone armor. The mouth is located on the bottom of the skull, indicating that it is an underwater organism.
"The Bulbophyllum rescinds the known body length of the carcass order," Towns said, "and its large body and dense thick armor provide a unique solution to the life problems of these rare turtles." ”
But armor aside, the happy days of the Overlord Ditch Scale Fish "soon" came to an end. Its sheer size may not help it survive.
"By the end of the Devonian Period, all carcass turtles were extinct," Downs said, "and we don't know exactly why the Tyrannosaurus go extinct, but large species tend to be at higher risk of extinction than petite species." ”
