[EX Q]: Passage: The Late Jurassic spans from 163 million to 145 million years ago. The Late Jurassic featured a massive extinction of sauropods and Ichthyosaurs due to the separation of Pangaea into Laurasia and Gondwana in an extinction known as the Jurassic-Cretaceous extinction. Sea levels rose, destroying fern prairies and creating shallows in its wake. Ichthyosaurs went extinct whereas sauropods, as a whole, did not die out in the Jurassic; in fact, some species, like the Titanosaurus, lived up to the K-T extinction. The increase in sea-levels opened up the Atlantic sea way which would continue to get larger over time. The divided world would give opportunity for the diversification of new dinosaurs. Question: What did the separation of Pangaea cause to become extinct?
[EX A]: sauropods and Ichthyosaurs

The FWS will then assure that if, in the future the unlisted species becomes listed, the landowner will not be required to do more than already agreed upon in the CCA. Question: How does a CCA impact unlisted species?

enhance or maintain habitat of unlisted species which are declining and have the potential to become threatened or endangered
