nannofossil

(also nanofossil)

noun ˈnanəʊˌfɒs(ə)lˈnanəʊˌfɒsɪlˈnanōˌfäsəl

The fossil of a minute planktonic organism, especially a calcareous unicellular alga.
Example sentencesExamples
- As revealed by light microscope and SEM studies, nannofossils are moderately to well preserved with slight indications of overgrowths in the marlstones.
- The same samples as used for geochemistry were investigated for their content of calcareous nannofossils.
- These deposits were correlated with the calcareous nannofossil zones NP 24 and NP 25.
- This paper presents high-resolution data from calcareous nannofossils, planktic Foraminifera, palynomorphs and stable isotopes for the Late Albian OAE Id.
- An increase in the relative abundance of boreal nannofossils in Romania during the late Valanginian also supports low temperatures within Tethys during this time.
- In the seas, the calcareous nannofossils were still in evidence but in shallow waters the benthonic nummulite and other larger foraminifera became very abundant.

Origin

1960s: from nannoplankton (variant of nanoplankton) + fossil.
