"Welsh Rocks Reveal Earth's Earliest Creatures"

Fossils discovered in Welsh rocks in the 1970s have been dated to 564 million years ago, revealing details about some of Earth's earliest creatures. The disc-shaped invertebrates, found in Carmarthenshire, likely lived in shallow waters along the coast of volcanic islands during the Ediacaran period. These ancient organisms, too primitive to be described as animals, are unlike any other forms of life and are considered the oldest in Wales. The breakthrough in dating the fossils was due to the work of a Pembrokeshire-born PhD student, Tony Clarke, who has been working on radiometric dating at Curtin University in Perth, Western Australia.

Ancient Worms Revived After 46,000 Years in Siberian Permafrost

Scientists have successfully revived ancient worms that were frozen in Siberian permafrost for 46,000 years. The microscopic worms, known as nematodes, were found in the permafrost and brought back to life in a laboratory. This discovery provides insights into the ability of organisms to survive extreme conditions and has implications for astrobiology and the search for life on other planets.

"Uncovering Earth's Ancient Predators: Mysterious Lifeforms Found in Billion-Year-Old Rock"

Scientists have discovered the remains of an ancient lost world of mysterious organisms, known as "protosterol biota," that existed 1.6 billion years ago in Australia. These microscopic creatures help fill in a major gap in human understanding regarding the early evolution of eukaryotes, which are believed to have existed long before plants and animals emerged. The researchers hope to learn more about this ancient lost world by studying the organisms more in-depth and even learn more about evolution's secrets.

Uncovering a Billion-Year-Old Lost World of Life on Earth.

Scientists have discovered ancient organisms called Protosterol Biota in billion-year-old rocks from northern Australia, which could be the oldest remnants of human lineage. These microscopic creatures are part of a family of organisms called eukaryotes and lived in Earth’s waterways about 1.6 billion years ago. The discovery of the Protosterol Biota is the result of 10 years of work by researchers from the Australian National University and was published in Nature. The researchers found that the molecules had a primordial chemical structure that hinted at the existence of early complex creatures that evolved before the last eukaryotic common ancestors (LECA) and had since gone extinct.
