The Laurel Formation, also known as the Laurel Limestone or the Laurel Dolomite, is a geologic formation in Indiana and Kentucky. It preserves fossils dating back to the Silurian period.
The Cordell Formation is a geologic formation in Michigan. It preserves fossils dating back to the Silurian period.
The Pointe aux Chenes Formation is a geologic formation in Michigan, USA. It preserves fossils dating back to the Silurian period.
The Tymochtee Formation is a geologic formation in Ohio. It preserves fossils dating back to the Silurian period.
The Arnheim Formation is a geologic formation in Ohio. It preserves fossils dating back to the Ordovician period.
The Louisville Limestone is a geologic formation in Ohio. It preserves fossils dating back to the Silurian period.
The Lilley Formation is a geologic formation in Ohio. It preserves fossils dating back to the Silurian period.
The Bisher Formation is a geologic formation in Ohio. It preserves fossils dating back to the Silurian period.
The Golconda Formation is a geologic formation in Kentucky. It preserves fossils dating back to the Carboniferous period. In Indiana, the Golconda, it is called the Golconda Limestone and is part of the Stephensport Group.
The Harrodsburg Limestone is a geologic formation, a member of the Sanders Group of Indiana Limestone, of Mississippian age. It was named for Harrodsburg in southern Monroe County, Indiana by T. C. Hopkins and C. E. Siebenthal. It is made up primarily of calcarenite and calcirudite. It also may include some beds of dolomite and shale.
The Osgood Formation, also known as the Osgood Shale is a geologic formation in Indiana, Kentucky, and Ohio. It preserves fossils dating back to the Silurian period.
The Salamonie Dolomite is a geologic formation in Indiana. It preserves fossils dating back to the Silurian period.
The Waldron Shale is a geologic formation in Indiana. It preserves fossils dating back to the Silurian period. These fossils comprise at least three different benthic communities primarily living in the inter-reef, deep waters that were stable for much of the Wenlockian epoch. Many of these fossils are found most frequently around microbioherms constructed by small encrusting organisms which protected other species from the effects of storms.
The Kokomo Formation is a geologic formation in Indiana. It preserves fossils dating back to the Silurian period, most notably sea scorpions.
The Louisville Formation is a geologic formation in Indiana. It preserves fossils dating back to the Silurian period.
The Sugar Run Dolomite is a geologic formation in Illinois. It is a finely-bedded dolomite, preserving fossils dating back to the Silurian period. This formation is named for the Sugar Run stream in Joliet, along which it is well exposed. The dolomite is off-white/grey on freshly cut surfaces, but over time oxidizes to a distinctive cream yellow color, due to trace presence of iron. It is a member of the Niagran series.
The Manitoulin Dolomite is a geologic formation in Ontario. It preserves fossils dating back to the Silurian period.
Distomodus is an extinct genus of conodonts.
The Hendricks Formation is a geologic formation in Michigan. It preserves fossils dating back to the Silurian period.
The Rapson Creek Formation is a geologic formation in Michigan. It preserves fossils dating back to the Silurian period.
The Bush Bay Formation is a geologic formation in Michigan. It preserves fossils dating back to the Silurian period.
