Where do you get this? Have you ever cracked a paleontology book in your life?
Here's something I'm reading in a current Nature article:
Placentals represent most living mammals (1,135 out of 1,229 genera) and are found on all continents and in all oceans10. Placentals and their extinct stem lineage constitute the Eutheria. More than 4,000 extinct eutherian genera have been named that represent the 65 million years of the Cenozoic, and the majority of these have been assigned to modern placental lineages11. In contrast, only about 40 eutherian genera are known from the 80 million years of the Cretaceous4, 6, 11.
Let me repeat that.

Look at this. There are almost four times as many extinct eutherian genera as living ones. This leads you to a couple of ridiculous conclusions:
And I haven't even checked reptiles and birds yet, that was just what I happened across. :-)
Please show me where the bible mentions the word “species”..... It is strangely missing from mine.
