I hope this is the place to learn some knowledge. My husband works in a quarry in Devon and after a blast has come across these four beautiful giant concretions? Which were in a pocket together. I would be interested to know what they are made of. We have washed the one which was the smallest - the only one he could carry -the colours seem to be very red with some orange. There is also another which is around 1.2meters across which we will be adding to our set. I would be interested in any information regarding our new found rocks

The front, back, side and bottom of whatever this could be? I could not find anything to measure it with but for now hopefully the pictures alone help for the meantime. The shape of it reminds me of a bone for some reason so that's my guess as to what it could be; not quite sure of what this texture on it is though, i scraped a bit of it off fairly easily and it was dusty brown coming off of it, but not too hard when scraping the surface it barely had any resistance. I tried scraping the exposed part of my other find; the iron concretion to compare the 2 and the concretion was much more durable on it's exposed part to try ruling out if it is just another ironstone concretion. It was found in the same brook called "big brook preserve" in central new jersey in the united states. Another possibility that I've came up with is that this find might be a concretion but not nearly as old and formed yet. Right now it could be anything. Thank you to whoever responds and helps with this post; very much appreciated.
