    I am studying the historical populations of all living creatures(demographics). I am looking for some accurate fossil records (data and charts). The desired data would include, the number of fossils found during a certain period of time, geographical location, what species they were, and probable cause of death (this field is not totally necessary, but would be nice).
    Thanks.

    It has been a week since I asked this question. Just giving it a bump as I need a reliable database for fossil data. Surely there must be a database or something out there?

    Thanks.

    To be honest I am rather confused as to what you are looking for.

    "The desired data would include, the number of fossils found during a certain period of time"

    does this mean during a collecting trip, field season, particular geologic period, .....?

    "geographical location"

    single site, region, formation,...?

    "what species they were"

    this I understand, but will point out that many fossils are never identified/identifiable all the way down to species.

    "probable cause of death (this field is not totally necessary, but would be nice)"

    this would not be applicable to many fossils, eg plants, fish, invertebrates etc... sorry

    Paleoichneum - Sorry if my request was not clear. I will try and clarify.

    My study is on population so the data I need is relevant to that.

    The study is for multiple species, but for now I will just use humans as an example, to hopefully make things a little more clear.

    1. Number of distinct humans that have had fossils found for them. (Again info that would help determine a relative population during a "particular geologic period") I realize not all humans or other species leave fossils, but I this information will be used with other data. (So, this gives me an approximate number of the species in question)

    2. For each human discovered, where was the fossil discovered? What area of the globe was it found? (This allows me to see geographically where the population of species were on the earth during a certain time period, and how they spread.)

    3. For each human discovered, what is the estimated time period the human was alive. What was the carbon dating of the fossil?

    My goal, is to have a fairly accurate model, of where species started from, how they migrated the globe, and approximately how many of each species was on the earth at each time period in history.

    I have looked for data, but so far have not been able to find anything that has been of real use. If there is no database out there with this data, someone should start one. It would be such a huge tool if everyone put their findings a one large database that could be searched for things like this.

    Thanks, I hope this makes it a little more clear.

    Hmmm, that I know of no comprehensive database of all fossils ever found exists. some sites produce only a few specimens ever, while others can produce hundreds or thousands The site I work at half the year has produced many new taxa which we know only from a single specimen, at the same time every other rock you kick at the outcrop has part of a Metasequoia occidentalis branchlet on it. I'm assuming that when you use the term species you are meaning taxon as many fossils are never identified/not identifiable to the species or even the genus level. Most fossils are not carbon dated as they are much to old, (c14 dating is good to about 50,000 years old) but most sites have good dates from other measures so you shouldn't have too many problems there at least.
