IDENTIFICATION OF FOSSILS

The beginning collector is usually content to know if his specimen is a

clam or a snail or a fern or a palm leaf. But as the collection grows,

it becomes increasingly desirable to know the scientific name of each

fossil.

When he starts to identify fossils it may be helpful to show them to a

geology teacher if a college or university is nearby. Most teachers are

glad to be of help and will probably have similar specimens in their own

collections. As all colleges do not have geology departments, a list of

institutions with geologists on their faculties is included at the end

of this section of the handbook (p. 27). In addition, many of the

science teachers in the public schools are familiar with fossils and can

give helpful suggestions as to how to classify material.

Museums are also good places from which to get help. If the museum has a

geological collection, it will be most helpful to compare specimens with

the fossils in their collections and to ask the museum personnel for

advice. In addition to the above sources of information, local

professional geologists are usually familiar with the geology of the

local area and the paleontological literature of the region.

Possibly local librarians can recommend books, encyclopedias, or other

publications that will be of help. Members of a local rock and mineral

club, if one is available, are another source of information. Many times

these collectors can pass along good ideas and tell exactly which books

to consult.

After books or journals describing the fossils of the area have been

located, the collected specimens should be closely compared with any

illustrations that are shown. Each fossil should be examined carefully,

its more characteristic features noted, and it should again be compared

with the illustrations and descriptions in the book. The phylum or class

to which the specimen belongs should be determined first. For example,

the genus and species of a certain fossil may not be known, but it looks

like a snail and accordingly it is named a gastropod (for class

Gastropoda, the snail class), and this is, at least, a start in

determining the scientific name of that particular fossil. The

descriptive material in the text of each reference will usually point

out the more detailed features which will be diagnostic of the genus or

species.

The illustrations and descriptive material in this publication will also

be of considerable help in identification. Many illustrations of the

more common invertebrate fossils have been included, but the publication

was not designed primarily for use in fossil identification. Rather, it

is intended to guide the amateur or student who is interested in fossil

collecting, and to furnish suggestions as to how collecting may be more

effectively pursued.
