Solution
The correct option is D Ordovician
The Ordovician is best known for the presence of its diverse marine invertebrates, including graptolites, trilobites, brachiopods and the conodonts (early vertebrates). A typical marine community consisted of these animals, plus red and green algae, primitive fish, cephalopods, corals, crinoids, and gastropods. A burst of evolution went on to triple the diversity of marine animal life in the space of 50 million years.Thus, the correct answer is option D.
