Research News

Thanks to ongoing research by Dr. Steve LoDuca, Department of Geography and Geology, Eastern Michigan University, Ypsilanti, Michigan, we can now provide the following information.

This specimen had been identified as Acanthograptus granti but has now been identified as Inocaulis plumulosus. It is still undetermined whether it is algae or graptolite. Current thinking still leans towards algae. This specimen can be found in The Silurian Experience on
​page 127.

This specimen had been identified as Inocaulis ramulosus but has now been identified as Acanthograptus, probably the species walkeri.
This specimen can be found in The Silurian Experience on page 128.
Picture
This specimen is currently unidentified but is likely Acanthograptus with the species uncertain at this time.
This specimen can be found in The Silurian Experience on page 134.
Acanthograptus are graptolites.

This is Thallograptus cervicornis. It is uncertain whether it is a graptolite or an algae.
An example of this species was not included in The Silurian Experience due to it being identified as Inocaulis.
