A tiny body from 550 million years agoSourced
An ancient, slender fossil may belong to an early molting-animal lineage.
Fossils about 560 to 550 million years old from Australia and Newfoundland were described as Uncus dzaugisi in 2024. If its proposed placement among ecdysozoans is correct, it may be among the oldest known members of the group that includes arthropods and tardigrades.
A small fossil could extend a major animal lineage deep into the past.
