A newly-identified species of spike-covered worm with legs, which lived 500 million years ago, was one of the first animals on Earth to develop armour for protection.
The discovery of a 500 million-year-old fossilised brain has helped identify a point of crucial transformation in early animals, and answered some of the questions about how heads first evolved.
One of the most bizarre-looking fossils ever found - a worm-like creature with legs, spikes and a head difficult to distinguish from its tail – has found its place in the evolutionary Tree of Life, definitively linking it with a group of modern animals for the first time.
New fossil find reveals that trilobites were able to roll themselves up defensively far earlier than was originally thought
Unique fossils literally ‘lift the lid’ on ancient creature’s head to expose one of the earliest examples of food manipulating limbs in evolutionary history, dating from around 530 million years ago.
