Mazon Creek Best Of The Best Elonichthys Remotus Schultz And Bardack, 1987
RCFossils posted a topic in Member Collections
There are 8 species of paleoniscoids currently described from the Mazon Creek Deposit. While all are relatively rare, the vast majority can be identified as Elonichthys peltigeras and Elonichthys hypsilepus. The other six species are known from very few examples (sometimes only one or two). Almost all Mazon Creek paleoniscoids are juveniles but there are a few larger examples. There are also some isolated body parts of larger individuals. The fact that most Mazon fish are juveniles and often poorly preserved can make identification difficult. To compound the problem there needs- 2 replies

Hi all, This specimen was found in a black shale layer that lays directly and uncomfortably upon the Duquesne Limestone, which is Late Pennsylvanian age. It was found in the suburbs of Pittsburgh. Both the shale and limestone are filled with vertebrate fossils, especially the scales, teeth and spines of paleoniscoid fish. As far as I know there is no species list from the shale but Elonichthys has been reported. I know skull roofs can be very diagnostic so any rough estimates of genus would be very helpful! I apologize for the picture quality, my phone is a brick.

Identifying Paleoniscoid Fishes From Linton Ohio, Upper Pennsylvanian
dshamilla posted a topic in General Fossil Discussion
If you have ever collected fish from the classic vertebrate locality near Linton, Ohio or have obtained fish specimens from there, I would like to share some of what I have learned about the type of fish called paleoniscoids (also spelled palaeoniscoids) that occur there. Paleoniscoid fish have thick, rhomboidal scales made of dentine-type bone with a surface of hard enamel-like material called ganoin and on the external surface of the ganoin there are pits and fine canals. They resemble (body-wise) what most people think of commonly as a “fish-shape” except they have “armor-like” scales. T- 12 replies
