Found this today, which I think is a fossil of leaves? Thanks! Location: Monterey Formation shale, Monterey County, California (Miocene) Outside of Carmel Valley, near Garland Ranch, among pea crabs (Pinnixa sp.) Description: About an inch and a half in length (I could get exact measurements). It looks like they have a complete margin(?) with a central midrib and veins that alternate. From a single split, so, positive and negative sides.

Greetings, everyone. I spent the other day on the east side of Ventura County breaking open sedimentary rocks. I'm not experienced enough with that sort of material to positively ID it but I think it was siltstone. There was a leaf and something else on both sides of one of the rocks. I've been having a hard time figuring out what the "something else" is. It measures about 35 by 14 millimeters. I took a few pictures of both sides under different lighting conditions to help bring out some of the finer details. It comes from the Modelo Formation (Miocene). Thanks ahead of time for any help in figuring out what it is. Here are pictures of the first side: Some pictures of the second side:

I’d really appreciate any help on this: I just bought a couple of fossil specimens that were described as: Middle Miocene, Monterey Shale Formation. Tranquillon Peak ashfall grading into regular sediments. Rezner Quarry in Tempesquet Canyon, Santa Barbara County, California. The fossils were collected in 1999. I’m trying to find out anything more about the locality. Has anyone ever heard of this quarry? Does anyone know where it is? Does anyone have any suggestions for contacting someone who might know more? I’m not looking to collect there (I live hundreds of miles away!); I would just be grateful for any additional information. Thanks a lot!

I've been fairly absent from the board the last month and the reason is I got crabs, and the good kind. It was posted a couple years ago by a one time poster/user about Pinnixa galliheri (Rathbun, 1932) from Atascadero, CA, I had since been looking for similar outcrops in the area, considering his front yard is off limits to collecting. A friend of mine, another fossil nut, found a small outcrop by chance while on a walk. The shale is denser and more silicious than the classically known localities near Carmel, CA, also has more iron staining in certain layers, while others we call "Ghost Crabs" since they are white on a grey petroleum chert rich shale. First I'll start with a less common specimen from the Monterey/Carmel area, Parapinnixa miocenica, as described by Mary Rathbun in 1932. I purchased this item on eBay last week, got it in the mail on Monday and prepped it Tuesday, could tell it was just begging to be prepped out I use a PaleoTools MicroJack #2 under magnification for this work, I'm still learning, if you have suggestions please feel free to share. Here is a Before/After sequence:

These were embedded in the rocks in the beach at Point Lobos. The first one is about 12 inches long, the second one is about 8 inches long, and the last one is about 18 inches long. They were all very close together, and unlike the rest of the rocks around. Any ideas?
