Question
Asked 19 April 2024

Dear RG community, can you help us to identify these palynomorphs?

Hello,
These NPPs were found in modern soil samples from the central Tunisian Dorsale mountain range. NPP6, 7, 8 and 9 seem to belong to Glomus-type. Could anyone provide a more precise identification?
Thank you in advance for your help,
Best regards,
Yannick Miras

NPP6, NPP7, NPP9, NPP10 are fungal spores of which the first ones have germinated and have hyphae. NPP12 could also be fungal spores. NPP4 I suppose is also a fungal spore. NPP5 is an algal spore, looks like a dinoflagellate cyst such as pyxidinopsis but has no opening (archaeopyle). I can recommend the articles of Bas van Geel if you have unknown fresh water palynomorphs (e.g. Review of Palaeobotany and Palynology, 25 (1978): 1-120).

Npp3 looks like a testate amoebae
Npp5 a dinocyst
Npp6 is Glomus, a fungal type
Npp7 is also Glomus
Npp8 looks like a sedge pollen
Npp9 is Glomus
