New species Rebellatrix - ancient coelacanth fish diversity increased with the discovery of a new species of fossil identification results are stored in the museum. The new species is named Rebellatrix. The coelacanth is a primitive type of fish that moves slowly and predictably was entirely extinct before the discovery back in 1938. Hence, fish coelacanth still exist today are often called living fossils because no major change in 320 million years.
New species of coelacanth found this time is different from other types of coelacanth fish, both of which still exist and extinct. Most of the coelacanth has wide tails that are designed to move in a short distance after prey. Contrast, a new species of coelacanth has a tail like tuna, relatively lean and muscular, useful for capturing fast-moving prey.
"Strong and fork-shaped tail and slender body is an indication that these fish can reach and maintain higher speeds than other types of coelacanth," said study team member, Mark Wilson of the University of Alberta, Canada, who reported his findings in the Journal of Vertebrate Palaentology .
According to Andrew Wendruff, Rebellatrix name indicates that the Coelacanth is really a "rebel" or rebel. This fish can swim, explore the vast territory to find and catch prey with rapid movement. "This type can do anything that another coelacanth could not do it," he said.
Rebellatrix fossils collected in the 1950s and 1980s in the valley Wapti Lake Provincial Park in British Columbia, Canada. This area is a region on the west coast of the supercontinent Pangaea past.
Specimens are stored at the Royal Tyrell Museum in Alberta and the Peace Region Palaentology Research Center in British Columbia. Identification began in 2009.

Based on the analysis, Rebellatrix first appeared 250 million years ago, shortly after the extinction
Permian, when 90 percent of life on Earth extinct. Wendruff speculated that extinction make room for organisms that are able to move quickly as Rebellatrix to prevail. Thus, this type began to dominate in the future.
John Long, coelacanth fish expert from the Natural History Museum in Los Angeles County, California, said the findings suggest that the evolution is plastic, very flexible. According to Long, this finding is very surprising because after 200 million years, there are types of coelacanth have different lifestyles (fast motion) than other types of coelacanth (slow motion).
Even so, finally indicated that the Coelacanth is moving slower the win. Evidently, they are now still exists, while the fast-moving living fossil. Currently, only two types of coelacanth is still alive, the species Latimeria Latimeria chalumnae menadoensis in Africa and in Indonesia.
