Biometric data for the Paleogene calcareous nannofossil genus Hornibrookina from light and scanning electron microscopy
Biometric measurements from specimens from the calcareous nannofossil Hornibrookina were collected to help determine taxonomic and evolutionary relationships within the genus. Two sets of data are included. The first (Supplementary Data 1) are measurements taken from SEM microphotographs (published...
