480-million-year-old fossils found in Morocco

480-million-year-old fossils found in Morocco appears to strike a blow to the idea of a major extinction.
The international team of scientists who discovered the 1,500 fossils said their find shows that the dark stretch in the fossil
record more probably reflects an absence of preservation of fossils over the previous 25 million years.

The Moroccan fossils include sponges, worms, trilobites and mollusks like clams, snails and relatives of the living nautilus. Another fossil was similar to today’s horseshoe crab, a biological throwback familiar to beachcombers. Now, the scientists said, its antiquity appears to be even greater — some 30 million years earlier than previously thought, possibly in the late Cambrian.
