Where to look for Order, and Family for my fossils?
Mediospirifer posted a topic in Questions & Answers
I'm looking to add a specimen to Collections (my blastoid, seen at this link: LINK), and I'm hung up on Order and Family. My field guide gave me the genus and species, and Wikipedia gave me the Class, but I can't seem to find any sites online that routinely show Order and Family--except TFF's Collections, which doesn't (yet!) include any blastoids. Can anyone point me to a resource where I can find this info for a variety of Devonian and Ordovician fossils?- 4 replies

I found this little tooth while going through some bulk sample from Jacksboro, TX, which is a Pennsylvanian area. I have found shark teeth there, but this looks more like a fish tooth. It reminds me of an Enchodus tooth, but I am not aware of any that were in the Paleozoic. Any ideas? The scale hash marks are 1mm. Thanks for any help.

Hi all, I am looking to obtain some more brachiopods for in my collection, mostly because I think that it's a fascinating group of animals. Unfortunately, I do not have many of them. Therefore I'm asking the help of you all! This is what I want: Brachiopods (spiriferid or not) from any continent (preferably not from Europe) from the Paleozoic. I don't need a lot, just a few different ones to widen my collection! Having from many different locations would be nice too. I already have the following though, and as to avoid having duplicates I am not interested in these: Platystrophia from Maysville (KY, USA) Punctopsirifer from Beckenridge (TX, USA) Terebratula perforata from Kaloot (NL) Cyrtospirifer verneuilli from Barvaux-sur-Ourthe (BE) Atrypa reticularis from Eifel (DE) Cererithyris and Kallirhynchia from Lion-sur-Mer (FR) If you have one of those species (but from another location), I'm still interested! Or if you have other species but from the same location, same goes! What I don't want is to have the same species from the same location. In return, I have a selection of different (mainly) European fossils, ranging from shark teeth to seashells (and a few brachiopods ), and many other things. I also have several fossils from closed locations! If you're looking for anything specific yourself, then you can always ask me and I'll see what I have. If you're interested and have anything to propose, please send a PM! Thanks in advance! Max PS: for international shippers, make sure that the shipping costs to the Netherlands are not too high. I'm willing to ship to anywhere, but I just want to make sure that this is both ways! (No Track & Code needed; no signing needed; no priority needed; envelope is better)

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. They are set apart from the chondrichthyans (sharks), the dipnoans (lungfish) and the coelacanths, which also occur in the Linton cannel. The Linton paleoniscoids can be divided into two family groups, the elonichthyids (1 species) and the haplolepids (6 species). I’ve attached a pdf file called “1. Identifying Linton Paleoniscoid Fish” which describes the fishes for species identification. I tried to keep the terminology minimal, but to describe the differences some was necessary. To aid in identifying haplolepid species, I have put together an illustration called “Linton Haplolepids”. The accompanying jpegs show the illustration and most of the different paleoniscoid types. Because I no longer have any specimens (see pdf file: “2. My Linton Collection and Recollections”), I cannot provide photos of two of the species. I hope this information will be useful and bring about more interest in learning about and collecting in coal measure deposits wherever they occur. 1a Identifying Linton Paleoniscoid Fish.pdf 2 My Linton Collection and Recollections.pdf- 12 replies

There is a small road cut exposure I like to frequent in the Plattsburg fm. where the Hickory Creek shale is excavated at a relatively shallow angle. The whole formation it extremely fossiliferous, but specimens with great preservation require diligent and persistent searching. But, to the subject of this post, an interesting means of finding those great fossils is in timing a good rain with a day or two of drying and wind erosion. The shale is very loose and it seems that what happens is fossils (and of course 'just rocks') of certain weights and sizes hold their ground while the shale erodes away underneath them. I've affectionately, though probably not originally, coined them as being pedestaled. Here are a few recent examples: Orodus(?), Cladodont fragment, and Horn Coral
