The shark Carcharhinus sp. from the Middle Eocene of Jamaica and the Eocene record of Carcharhinus

ABSTRACT:
An upper tooth of a previously unrecorded species of the shark Carcharhinus was recovered from the Middle Eocene of Jamaica. This represents one of the oldest examples of the genus, which today is one of the dominant groups of predators within a variety of tropical environments. This is also the oldest record of a carcharhinid shark from marginal marine facies and confirms that the early radiation of Carcharhinus occurred within Tethyan regions
