These images are from my MSc project titled 'Taxonomic and palaeobiological description of South African mosasaurids', which I completed in 2020 and can be found through OpenUCT: Woolley, M. R. (2021). Taxonomic and palaeobiological assessment of the South African mosasaurids.
They are histological micrographs of a fossilised Prognathodon tooth (CGP/1/2265) from Pondoland, Eastern Cape. More information about the tooth and specimen in published article: Woolley, M. R., Chinsamy, A., & Caldwell, M. W. (2022). Unraveling the taxonomy of the South African mosasaurids. Frontiers in Earth Science, 10, 971968.
These images were taken in 2019 at the University of Cape Town, Department of Biological Sciences by Megan Rose Woolley.
