Symplassosphaeridium
The microfossils that I recovered from drill core of the lower Chamberlain Formation are mostly made up of relatively large (i.e., greater than 120 micrometers in size) pluricellular aggregations of...

Synsphaeridium
Synsphaeridium (along with Coniunctiophycus, Symplassosphaeridium and possibly Satka) is a relatively large, pluricellular aggregation fossil that I recently discovered in drill core of the...

Tappania
Tappania are microfossils found mostly in shale that range in age from the late Paleoproterozoic to the middle Mesoproterozoic. They are known for being morphologically complex, with tubes (known as...
