Mercanites Marshall formation David Thompson

Submitted on 2008-03-12 by David Thompson

Location (approximate): Jackson, Jackson, MI

Strat unit: Marshall formation

Submitter notes: This shows the more complex suturing of the amminoids compared to the nautiloids which are straight with simple rings. Unfortunately there is not too much of the fossil visible so identification is tentative. This is a typical example of the 'rusty' look of fossils in the Lower Marshall sandstone from th 'blue ridge esker' south of Jackson, MI

amminoid , gastropod Marshall formation David Thompson

Submitted on 2008-03-12 by David Thompson

Location (approximate): Jackson, Jackson, MI

Strat unit: Marshall formation

Submitter notes: This is the reverse side of the previous example showing a gastropod (?) and a part of ammoniod (?) centered in this small block. This sandstone turns up in almost every parking lot in Michigan where cobble stones are used as fill around buildings. These were collected in the esker, however. A 25 cent piece for scale
