"Beautiful nightmare" cancer with animated eyes open



"This gives us information about how new body shapes can evolve over time," said Luke in an interview "Washington Post" in Thursday.

Luke said he had found the mountains in Pesca, Boyaca, in Colombia in 2005.

Luke, a geology student at the time, said he was trying to look for fossils when he discovered a sample of crustacean specimens – shrimps, lobsters and crabs with large, bulbous eyes.

Luke and his research team, who are studying well-preserved fossils found in Colombia and the United States, publish their discoveries in the magazine Scientific Achievements on Wednesday.

The study gives an idea of ​​a being that is so peculiar that it has been called the "crab patch".

So what do we know about this wide open eye?

The cancer lived during the middle of the chalk – when the dinosaurs ruled the earth, the earth masses were in motion and the oceans formed. And depending on where the fossils were found, she lived in present-day Colombia, North Africa and the United States, particularly in Wyoming.

His name, Callichimaera perplexa, means "a confusing beautiful chimera," a hint of a Greek mythological creature that has body parts of different animals. It makes sense. Scientists say the cancer has a "mosaic of parts of the body," including unprotected eyeballs shaped like a spindle body and leg-like parts, which suggests that in adulthood they have kept maggots.

The body of the cancer had a diameter of about 2.5 centimeters.

His eyes were so big that if he were a man, they would have big eyes like football balls.

His feet were built for swimming instead of crawling.

Her nails make him a powerful little hunter.

And if the cancer lived another 95 million years, it would probably be Hollywood.

Lucke, the lead author of the study, told Live Science that "I call it my wonderful nightmare because it was so beautiful and disappointing" to understand the researchers.

Heather Bracken-Grissom, an evolutionary biologist at the Florida Interior University who specializes in decapods, says that today more than 7,000 crabs live.

This "strange find" will allow scientists to reassess what they know about them, she said.

"This new transient fossil makes us rethink how crabs have evolved over time because they bring this unique body shape that we have not been aware of before," she said.

She said she revealed "an early birth in the tree of cancer of life."
