Identification help: Freshwater bryozoa statoblast from East Africa

Identified!

This is a statoblast of the species Lophopodella capensis or possibly Lophopodella stuhlmani. Some information on the distribution of this freshwater bryozoa can be found here.

Bryozoa statoblasts like these were found in the late Holocene sediments of Nyabuiyabui Swamp, a freshwater swamp on the Mau Escarpment in Kenya, at 2900 m asl. If it is possible to identify this to the genus or species level please contact us! It may yield some information on the evolution of this important wetland.

It appears to be 2-3 mm or so in diameter, has a darker center, and rounded hooks at each end. Possibly from the Lophopodidae family?
