Statistical fossil distributions

Would it be possible for scientists to take all the fossils ever found of a certain species, and assuming the finds would be evenly distributed among all different species based on the numbers that have existed for all time going back to a certain point, could scientists estimate a very rough number of how many creatures of that specific species ever existed on this planet throughout history? Or perhaps, not that grandoise, but estimate the percent of the animal population that that species represented at a specific time range in history? For example, if they found 90 triceratops fossils during the X period, and 9000 non-triceratops fossils during the X period, could they estimate the percent of the animal populations that triceratops made up in that time period was 1%? Or do they not have enough fossils to even do this and make it statistically accurate enough? Or perhaps it would be skewed because some areas are hard to dig for fossils in, like African countries involved in civil wars...

nope

What is science if it cannot do such a simple thing?

To do that, they would have to have some kind of estimate of the percentage of dinosaurs that actually ended up as fossils. Becoming a fossil is an extremely finicky series of conditions, such that actual fossilization is rare.

Say we find thirty-five fossilized specimens of Species X. The only thing that can reliably tell us is that thirty five specimens of Species X existed. That doesn't tell us anything about how many Species X were ever alive; the number could be fifty, or it could be fifty thousand.

What can do it?

science, if science actually worked =(

triceratop #91 fell into a lava flow... oops
