One Hundred Years Later Sir David Attenborough body may have turned to dust, but the fossilized sea creature thought to represent Earth’s earliest animal carnivore will continue to bear his name.
discovered in Charnwood Forest, Leicestershire, where Attenborough hunted. for Fossilized as a child, this creature is 20 million years older than what was previously thought to be the oldest carnivore.
Paleontologists have named it Auroralumina attenborough, in honour of TV presenter. first part of his name is latin for morning lantern, in confession of this is great age and resemblance to a burning torch, and the creature is believed to have used set of densely packed tentacles capture food in Earth’s early oceans.
Charnwood Forest is famous for his fossils. Although Attenborough dug there as a child, he avoided the rocks where auroralumin was found. “They were considered ancient that they date back long before the beginning of life on planet. So I never looked for there are fossils,” he said.
A few years later, in 1957, fern-like the impression was discovered by Roger Mason, the youngest boy at Attenborough School. The discovery turned out out to be one of oldest fossilized animal, and was named Charnia Masoni, in Honor Mason.
“Now I – almost – caught up with We are really excited about him,” Attenborough said. who It has more more than 40 species named after him, from the Madagascar dragonfly to the dandelionlike hawk found Only in brecon lighthouses in South Wales.
Auroralumina is part of of treasury of more over 1000 fossils discovered in 2007 when team of Researchers from the British Geological Survey spent more than in a week in Charnwood Forest, clearing a 100m stone surface. with toothbrushes and nozzles, before using rubber mold for capture impression of its lumps and bumps.
The fossil was dated at the headquarters of the British Geological Survey. using tiny radioactive minerals in the surrounding rocks, called zircons, which act as a geological clock.
Related to group including modern corals, jellyfish and anemones, 560m year-old specimen first of kind. Its discovery was announced in The ecology of nature and evolution is called into question when contemporary groups of animals appeared on Earth.
“It is generally accepted that modern groups of animals like jellyfish appeared 540 million years ago in Cambrian Explosion. But this predator is 20 million years older than it,” said Dr. Phil Wilby, head of paleontology at the British Geological Survey. who helped discover.
“This is the earliest being that we know of have a skeleton. As long as we only have found but very interesting know there must be others out there holding key when the difficult life began on Earth.”

Dr. Frankie Dunn of Oxford University Museum of Natural history, who blown away out detailed study, said: “It’s nothing like anything else we have found in fossil record at that time.”
While body plans of other fossils from this period have nothing to do with these of living animals are one clearly has a skeleton, with densely packed tentacles that would wave around in water captures passing food, significantly like today corals and sea anemones do it,” she said.
It may have originated from shallower water than the rest of fossils found in Charnwood. “All of fossils on the cleaned stone surface was attached to the seabed and knocked down over in same direction flood of removal of volcanic ash down submerged leg of volcano, except one, A. attenboroughii, Dunn said. “It lies at a strange angle and has lost its base, so it looks like it was swept away down slope in flood”.
