Tennessee Girl discovers 475 million year old trilobite fossil



  Fossil Museum

Walking around a lake in Tennessee, a young girl discovered an artifact that was later considered 475 million years old. Reports from Tennessee revealed that 11-year-old Ryleigh Taylor, who lived in the eastern region of the area, was walking along the banks of Douglas Lake to find the 475-million-year-old fossil.

Later, The results were transferred to a nearby university, the University of Tennessee, where palaeo-biology professor Colin Sumrall tested them thoroughly.

After examining the fossil, Sumrall reported that it belonged to an extinct marine animal known as trilobite. "When we look at fossils of trilobites, they mawk as they grow," Sumrall told ABC subsidiary WATE.com. "So what happens when the trilobite skeleton disintegrates into hundreds of small pieces? To find one in which all the pieces are intact is actually a lucky find."

According to an article published on Fossilera.com, trilobites grew in the Paleozoic world, which included one of the earliest known groups of arthropods. Trilobites were one of the earliest known groups of arthropods and thrived during the Paleozoic with more than 600 species.

Sumrall said he could one day picture Ryleigh as a great paleontologist

"I can Children my own age show that they do not have to sit and play indoors, they can actually go outside and find different things, "said Ryleigh WATE.

"I'm surprised it was right on the rock, for anyone who might have found it, but I'm very proud of it," said Tammy Taylor, Ryleigh's mother.

Ryleigh hopes that other children will come out and enjoy nature so they can see what they can find. Sumrall adds, "Finding such a thing could make the young man a whole career, and maybe one day she will become a great paleontologist."

It is not clear what the future holds for Ryleigh. At the moment she is happy to explore further. Ryleigh does not plan to keep the fossil. She wants it to be exhibited in a public museum so that others can enjoy it.

Trilobites

Trilobites proliferated and thrived throughout the Paleozoic world, which includes one of the earliest known groups of arthropods. They flourished to over 600 species at their zenith, including many exotic exoskeletons and unique feeding strategies. They are probably most closely related to modern horseshoe crabs.

Although Cambrian (521 mya) characterizes the occurrence of trilobites in the fossil record, they were already very diverse. They continued to multiply until their decline in the Devon and finally disappearance of the mass extinction in the Permian (250 mya).

Few points about trilobites:

  • Trilobites developed profound adaptations that make them among the most successful early animals ever. They patrolled, hunted and searched the oceans for over 270 million years.
  • Trilobite means "Three Laps". This refers to her body plan.
  • Trilobites occupied various levels of the food web including predator, scavenger hunt and prey
  • Trilobites skinned their exoskeleton similar to today's lobster.
  • Most trilobites are one of the first animals known to have a sense of sight. They had faceted eyes made of calcite crystals, something that is intrinsically trilobite.
  • Trilobites had sophisticated survival traits such as stems, spines, and the ability to self-register and protect their vulnerable parts from exposure.
  • Trilobites hatched from eggs and preceded by various growth stages.
  • Trilobites vary greatly in size and shape. They can be so small that they can be viewed with a microscope. They can also be quite big. Isotelus rex could be 2 feet long.
  • Trilobites are typically found by splitting slate and hard lime deposits.
