Well-Preserved, 462-Million-Year-Old ‘Marine Dwarf World’ Uncovered in Wales (Image credit- Tech Times)
A team of scientists led by the Nanjing Institute of Geology and Palaeontology of the Chinese Academy of Sciences (NIGPAS) has made an astounding find at Castle Bank, Wales: a remarkably well-preserved “Marine Dwarf World” from 462 million years ago.
Over 150 species, many of which are miniature versions of larger species, make up this amazing discovery.
At Castle Bank, Wales, a team from the Nanjing Institute of Geology and Palaeontology of the Chinese Academy of Sciences (NIGPAS) uncovered a 462 million-year-old “Marine Dwarf World” that was remarkably well preserved. More than 150 species, many of which are little, can be found at this fossil site. It is regarded as one of the most unexpected fossil sites in the entire globe.
By conserving soft tissue and complete animals, the Cambrian Period Castle Bank in Powys is a unique location that provides an unmatched window into the history of life.
Burgess Shale-type faunas, well-known locations named after the fossil-bearing deposit in Canada, are found in the region.
However, the majority of these sites are from the Cambrian period, which lasted from 542-485 million years ago, leaving a gap in our understanding of how marine life evolved in later eras.
Because of the Cambrian explosion, which saw the first appearance of a wide variety of complex animal life, the Cambrian period is regarded as a pivotal time in Earth’s history.
Numerous new species of organisms, including the earliest arthropods, chordates, and echinoderms, first appeared in the fossil record during this period.

The Castle Bank site, which dates back 462 million years and is unlike most of these sites, is from the middle of the Ordovician Period that followed.
With regard to the variety of fossils and exceptional levels of preservation, it is comparable to the best Cambrian deposits. Drs. Joe Botting and Lucy Muir found this unique assemblage in 2020 close to Llandrindod in central Wales.
