Ancient Sea Creature Helps Scientists Understand Early Arthropod Evolution
The Aegirocassis benmoulae is a newly discovered ancient sea creature that is helping scientists understand the evolution of arthropods. The fossil record shows that this animal had a surprising two set of dorsal flaps per trunk segment, opposing the previous viewpoint that early arthropods contain one dorsal flap per limb segment. Researchers believe the upper flap was equivalent to the upper limb branch of the modern day arthropods, while the lower flap was utilized for swimming. Watch the awesome video above on the discovery of the Aegirocassis benmoulae if you're interested.
