Some 480 million years ago the seven-foot-long Aegirocassis benmoulae swam in a shallow sea covering what is today the Sahara desert. This giant arthropod, much larger than arthropods existing today, was likely the biggest creature in the world at the time.
In the most comprehensive and thorough survey of its kind, an international team of scientists sampled, sorted and cataloged every arthropod species they could find in patches of Panama’s San Lorenzo rainforest. During their survey of areas summing up to roughly three acres, the scientists estimated that a 6,000 hectare forest houses 25,000 arthropod species, 60% to 70% of which
Paleontologists have uncovered the fossil remains of a 3-inch-long extinct arthropod in Yunnan Province, China, dating from the Cambrian period. What makes it particularly special is the fact that it provides an unusual example of preservation of the brain and nervous system, atypical for fossil records this old, but most interestingly it suggests that complex brains evolved much earlier than
