The science or study of fossils; an alternate term for paleontology.
From fossil + -ology (Greek -logia 'study of'). This is a redundant alternate form alongside 'paleontology,' which combines Greek paleo- 'ancient' with -ology.
Here's the interesting thing: 'fossilology' directly names its subject (fossils) while 'paleontology' indirectly does it (ancient beings)—both words mean essentially the same thing, showing how scientific language can have multiple valid paths to the same meaning!
