To tell your name the livelong day
To an admiring bog!

A More Ancient Origin of Animal-Built Reefs

The discovery of an approximately 548-million-year-old reef in Namibia, made of the world’s earliest known skeletal animals, suggests that these aquatic organisms built reefs before the Cambrian explosion (currently dated to have begun around 540 million years ago). Until now, the oldest reefs on record made of such metazoans had been dated to about 530 million years of age. The researchers’ findings not only imply that metazoans had been building reefs millions of years before the Cambrian explosion, but also that the evolutionary pressures that led to hard parts on and connecting animals, such as skeletons and reefs, were present millions of years prior to that great speciation event as well.
