An '''ichthyolith''' (from [Ancient Greek](/source/Ancient_Greek) ἰχθύς (ikhthús), meaning "fish", and λίθος (líthos), meaning "stone") is any disarticulated remains of a fish found in the [fossil record](/source/fossil_record), most often a [scale](/source/Scale_(zoology)), [denticle](/source/Dermal_denticle) or [tooth](/source/tooth). Ichthyoliths are found in nearly all marine sediment.<ref>{{Cite journal |last=Sibert |first=Elizabeth |last2=Cramer |first2=Katie |last3=Hastings |first3=Philip |last4=Norris |first4=Richard |date=March 2017 |title=Methods for isolation and quantification of microfossil fish teeth and elasmobranch dermal denticles (ichthyoliths) from marine sediments |doi=10.26879/677 |journal=Palaeontologia Electronica |volume=20.1.2T |pages=1–14|doi-access=free }}</ref>

The term was coined by Doyle, Kennedy and Riedel<ref name=":0">{{Cite journal |last=Doyle |first=Patricia |last2=Kennedy |first2=Grace |last3=Riedel |first3=W. R. |date=December 1974 |title=Stratignathy |url=http://www.deepseadrilling.org/26/volume/26dsdp.pdf |journal=Initial Reports of the Deep Sea Drilling Project |publisher=National Science Foundation National Ocean Sediment Coring Program and University of California Scripps Institution of Oceanography |volume=26 |pages=825–905}}</ref> (1974) to denote 'fish skeletal debris'.

The term 'stratignathy',<ref name=":0" /> proposed in the same paper for the time relationships of ichthyoliths, did not gain currency.
