In Late December, Minnesota is a land impossible to hunt fossils in. So when I took a trip to Ohio this Christmas, I was hoping mother nature would be kind to me and allow me to peak under a few rocks. While visiting my sister in NW Ohio, I convinced her to run up to Paulding with me to check out the Lafarge Quarry. Have seen postings about trilobites from there. We left Lima with no signs of snow on the ground. Two miles from our destination, the ground turned white, and snow was about 4 inches deep. Now I remember why I hated lake effect snow growing up in Ohio!! As long as we drove this far, we decided to travel on just to see the place. Fortunately, there had been a brisk wind that night and the tops of the rock piles were blown fairly clean of snow. Good enough for me. My sister thought I was nuts and remained in the vehicle. Here are the results of my short venture. Would love to visit this place in better conditions. I know how darctooth felt when he posted about his winter, snow covered excursion last week.

Taxonomy from Lowney, 1980. Diagnosis for the genus Parahaplolepis from Lowney 1980, p. 944: "The body is relatively long and slender, with a ventral lateral line. There are no separate dermopterotics in the skull roof. The anterior pit line of the skull roof extends onto the frontal from the parietal. The posterior margin of the skull roof is deeply embayed for the reception of the extrascapulars and posttemporals, and the latter two pairs of bones meet in the midline. The skull roof ornament consists of broad raised rugae or low tubercles. The maxilla (in the one species where it is known) has a rather tall posterior expansion. There is a small quadratojugal present behind the maxilla." Diagnosis for the species P. tuberculata from Lowney 1980, p. 945: "The frontals are covered with a randomly arranged pattern of broad rugae and smaller coarse tubercles. Their anterior border is usually indented slightly for the reception of the postrostral, and the posterior margin is more or less straight across. The latter characters serve to distinguish P. tuberculata from the other known members of the genus, P. anglica and P. canadensis, in which the posterior margins are obliquely directed anteriorly (Westoll, 1944; Baird, 1978). The fin positions are as follows: dorsal-23, anal-18, pelvic-8, caudal-27. The anterior lateral line scales are serrate on the hinder margin, but these serrations disappear at the level of the dorsal fin. The depth of the lateral line scales is approximately four times the width." Line drawing from Westoll 1944, p. 30: Identified by TFF member dshamilla.

Can anyone help with ID on this fossil please? I am told it is not fish part, but that is all I do know. Carboniferous, Pennsylvanian.

Pennsylvanian, all Lacoea cones??
-
Pennsylvanian, Megalopteris?
-
Pennsylvanian, both plates Danaeites, I believe. The one with the individual leaves has a fish scale in the upper left corner. Lots of fun today!
-
Had a very productive couple of hours at the site today. Not sure what these are? Pennsylvaanian

Hi everyone, I've recently done some shale collecting near the Rocky River in Ohio. I've found the shale in this area is late Devonian to Mississippian, and is good matrix to look for microfossils. I've collected some smaller material that I'm soaking and freezing to disaggregate, and also some larger material (1-6 inches). I wanted to know if anyone has had any experience with matrix from this area/from this period and if so are you more successful with smaller or larger material? Thanks very much!

Brought back from the site 7/6. Seed?
-
Found 8/1. Is this a Cordites Leaf?
-
Found this one today and not sure what it is?
-
Found this beautiful example of a Megalopteris last weekend. Lots of detail and very happy when I cracked open the rock!
-
Found this one today that I really like. It has 3 different specimens in it. Lacoea, Lepidostrobus Cone and I am not sure what the larger one is?
-
I do not believe I found one of these before.
-
Probably not the best fossil, but contains many species, which I find interesting.
-
Found today. Not sure what it is?
-
Found this today. Shape looks different than others I have found?
-
I found ones similar to this, but I think the shape is just a little different?
-
Found today.Not sure what it is?
-
Found 5 fish scales today. Some had pyrite on them, which was a first for me, but my fish also had pyrite on it. Here are 4 of them. The fifth was just too light to photograph.
-
Just one of the fronds, I think you call it? I believe it is Danaeites?
-
Small specimen, but I think this is what we are calling Danaeites right now. Just really happy to find one on my first day out!
