Wetheredella

Wetheredella is a genus of calcimicrobes known from the Silurian of England. It is suggested to be either a foraminifera, cyanobacterium or green alga. The genus is named in honor of the geologist Edward Wethered.
"Wetheredella" is characterized by calcified tubes encrusting a foreign body, with convex outer surfaces and inner surfaces coiled around the encrusted grain. Recently it has been shown that structures matching the description of "Wetheredella" can be produced by sectioning of "Allomena", meaning that "Wetheredella" is possibly a junior synonym of "Allomena".
