Kurt Komoda Posted May 31, 2023 Share Posted May 31, 2023 Hello! Drove down from Jersey and a good day at Douglas Point this past Sunday. Over 150 teeth in all, two nice- yet worn- Otodus teeth and a Paleocarcharodon orientalis. I also found this, and I don't know what it is. Maybe it's nothing. Photos are taken on a cutting board with a 1" grid. Link to comment Share on other sites More sharing options...
Fossildude19 Posted May 31, 2023 Share Posted May 31, 2023 Seems reminiscent of some native american pottery I have seen. Wait for other answers, though. 3 Tim - VETERAN SHALE SPLITTER VFOTM --- APRIL - 2015 __________________________________________________ "In every walk with nature one receives far more than he seeks."

DPS Ammonite Posted May 31, 2023 Share Posted May 31, 2023 (edited) Could this be a fragment of cast iron from a corn stick pan? That orange color looks like rust. Here is a Lodge cast iron corn stick pan: Edited May 31, 2023 by DPS Ammonite LINK and PHOTO removed My goal is to leave no stone or fossil unturned.

Done Drillin Posted May 31, 2023 Share Posted May 31, 2023 Yes agree with Native American pottery. You can see that is been sand tempered and impressed with a carved wooden “paddle” to make the pattern you see - referred to as “check” stamped in Florida. 1 Link to comment Share on other sites More sharing options...
sharkdoctor Posted May 31, 2023 Share Posted May 31, 2023 It is a shard of cord marked pottery. For identification, please see this site that is specific to Maryland. The link should open to a specific form of cord marked pottery, but feel free to explore to see if you can identify the form you have found: Diagnostic Artifacts in Maryland Various forms of cord marked pottery are fairly frequent finds in Maryland and Virginia. Congrats on finding one that hasn't been worn past recognition! 4 1 Link to comment Share on other sites More sharing options...
Kurt Komoda Posted May 31, 2023 Author Share Posted May 31, 2023 Wow, thank you, everyone! Cord-marked pottery is something I am wholly unfamiliar with, so I'm going to read up on it using the link @sharkdoctor provided. Also, I apologize for there being traces of cat hair on the sherd.

This is pretty obvious pottery, to my eye. Iron would not look like this, in my opinion. 1 Tim - VETERAN SHALE SPLITTER VFOTM --- APRIL - 2015 __________________________________________________ "In every walk with nature one receives far more than he seeks."

DPS Ammonite Posted May 31, 2023 Share Posted May 31, 2023 I agree that pottery is possible. However, rusting iron can cement sediment on the outside. We need an idea of the density and magnetism of the item. My goal is to leave no stone or fossil unturned.

I am currently attempting macro photography of its surface. Link to comment Share on other sites More sharing options...
Kurt Komoda Posted May 31, 2023 Author Share Posted May 31, 2023 (edited) I don't know if this clears anything up, but there are various particles embedded into the material. I do not currently have a scale sensitive enough to measure its mass. Edited May 31, 2023 by Kurt Komoda adding note about my lack of an accurate measuring device.

sharkdoctor Posted June 2, 2023 Share Posted June 2, 2023 The embedded material is called "temper." This is material added to the clay during the potting process to aid in firing. See this definition in Wikipedia: https://en.wikipedia.org/wiki/Temper_(pottery) 2 Link to comment Share on other sites More sharing options...
MarcoSr Posted June 2, 2023 Share Posted June 2, 2023 (edited) The specimen looks to me to be hardened iron stained matrix from one of the turritella lenses in the Aquia Formation with the pattern being the impressions of turritella internal molds. Certain areas along the Potomac are loaded with this. The close-up pictures definitely look like the matrix from one of these lenses. Also it looks like the individual impressions are different widths consistent with a turritella internal mold cast. If this is cord marked pottery, I've missed collecting a ton of it over the years. Edit: I now agree that this piece is cord marked pottery thanks to Julianna, old bones, PMing me some really convincing cord marked pottery (from her collection)pictures and an informative PDF, again with some informative pictures. Learning new things is one of the reasons that I'm part of TFF. After 50 years fossil collecting, I still learn new things all the time.

val horn Posted June 2, 2023 Share Posted June 2, 2023 No expert at all but i have seen pottery shards that look like it. Calvert cliff museum will be familiar with the local finds archeology dept local university is another choice for an expert opinion Link to comment Share on other sites More sharing options...
patelinho7 Posted June 2, 2023 Share Posted June 2, 2023 Such an interesting thread. When I first saw it, I thought it looked like rebar. It looks so iron/rust-stained. But after seeing everyone's opinions, pottery shard makes sense. Link to comment Share on other sites More sharing options...

The rest of the finds for the day were standard fare, except for the Paleocarcharodon orientalis (Extinct Pygmy White Shark) and the two larger Otodus obliquus (Extinct Megatooth Shark). 2 Link to comment Share on other sites More sharing options...
old bones Posted June 3, 2023 Share Posted June 3, 2023 That's a nice shard of native pottery @Kurt Komoda. I have a large collection of pieces decorated with various patterns including the corded one that others have correctly identified. I am including another one that is fairly common on the S.C. coast which is done with a pointy periwinkle shell. Corded: Periwinkle impressed: 3 1 Link to comment Share on other sites More sharing options...
