Summary
| Description |
English: Plumalina plumaria Hall, 1858 in quartzose siltstone from the Devonian of New York State, USA. (6.3 centimeters tall)
Seen here is a soft-bodied fossil that was first described & named in the 1850s, but is still considered a problematicum in the modern literature. This is a frond called Plumalina plumaria. Workers usually assign this organism to the hydrozoans (Phylum Cnidaria, Class Hydrozoa) or the gorgonarians (Phylum Cnidaria, Class Anthozoa, Order Gorgonaria), but it’s probably safest to refer to it as “incertae sedis” (“uncertain placement”). Stratigraphy: South Wales Member, lower Perrysburg Formation, Canadaway Group, Upper Devonian Locality: railroad cut on southern side of railroad adjacent to Rt. 26, southeastern side of Almond Lake, just northwest of Hornell, western Steuben County, western New York State, USA. |
