I read something about this only yesterday. In his foreward to the book
"Bones", Mark A Norell gives the following estimates:

number of extant species - between 1 and 10 million
number of fossils named by science - approx. 100,000

The former are alive today, the latter cover the previous 3.7 billion years.

"extremely sparse" is right!!
