American and British paleontologists have discovered in Morocco well-preserved fossils of 480-millionoletnego relative lobster roaches and spiders.
Two-meter creatures that live on the planet during the time of the Paleozoic era, reminiscent of a very large shrimp. But it does not have a finite and is powered by two flexible and sharp mustache-processes, which lured the food along with the water filter in your body. Mustache consisted of long needle-like fibers and whiskers were like whales and whale sharks gills. In these ancient giants in general was much more in common with modern whales than with tiny shrimp.


However, the strange creature was also attended by some of the features of modern arthropods - such as invertebrates with exoskeletons, among which spiders, insects, crustaceans and centipedes.

Fins or legs creature was not there. Scientists have come to the conclusion that it floated, bending his segmented body (on the surface of the shell was just two of a number of side plates).


Named a new species Aegirocassis benmoulae. The genus name has been collected from the name of Scandinavian sea demon Jotun Aegir and the Latin word cassis (helmet). The specific name sings Moroccan fossil hunter Mohamed Ben Mulu (Mohamed Ben Moula), who discovered the remains of creatures.

The fossils were found in the formation Fezuata (Fezouata). Now fossil sea monster are in the collection of the Museum of Natural History at Yale University Peabody.

Artist, reconstructed image of the animal, introduced him as a creature with a head like a squid and a body resembling the body of the shrimp. Eyes located on both sides of the head, and from the oral region were two jointed appendage covered with thorns with which A. benmoulae and lured a water plankton.


"A. benmoulae was one of the largest animals of their time," - said study co-author Allison Daley (Allison Daley) from Oxford University.

A study of the remains revealed that the animal led mainly passive lifestyle filtering allows, without straining, obtain plankton from the water and other nutrients. By the way, the fact that in the waters that once covered the territory of Morocco, could accommodate such a huge sestonfag may indicate that these waters are extremely rich in various nutrients.

"Apparently, filtering - this is one of the most ancient way of eating animals - says Daly. - However, the very first filter-feeders were much smaller and are usually attached to the seabed. This animal can be called ancient creatures, feeds by filtering freely swimming ".

The new species belongs to the now extinct family Anomalocarididae, which first appeared in the oceans around 520 million years ago.
