The cat gap is a period in the fossil record of approximately 25 to 18.5 million years ago in which there are few fossils of cats or cat-like species found in North America. The cause of the "cat gap" is disputed, but may have been caused by changes in the climate (global cooling), changes in the habitat and environmental ecosystem, the increasingly hypercarnivorous trend of the cats (especially the nimravids), volcanic activity, evolutionary changes in dental morphology of the Canidae species present in North America, or possibly even attributed to patterns of periodicity of extinctions (climatic/floral cycles called "van der Hammen cycles")

Famous quotes containing the words cat and/or gap:
“This morning I threw up at a board meeting. I was sure the cat was out of the bag, but no one seemed to think anything about it; apparently it’s quite common for people to throw up at board meetings.”
—Jane Wagner (b. 1935)
“The confrontation between America and Europe reveals not so much a rapprochement as a distortion, an unbridgeable rift. There isn’t just a gap between us, but a whole chasm of modernity.”
