awb8432390 Posted May 17, 2020 Share Posted May 17, 2020 Afternoon all. Found this little stone amongst the gravel on the driveway. We've found many fossils in the gravel including Belemnites, shells etc. But we've never seen anything like this. The surface is fairly smooth but you can feel slight 'pitting'. The inner material is coarse and hard, with a similarity to sandstone. The object is about 3cm in all directions, and almost spherical. Any help would be appreciated.

Kane Posted May 17, 2020 Share Posted May 17, 2020 Welcome to the Forum. Unfortunately, I also agree it is not an egg, but likely a tumbled cobble of some sort. The presence of pitting like this is likely on account of differential weathering. Usually with fossil eggs we'll see a bit of fracturing and cracks from the thin egg shell. I'm not sure if your area is known for finding fossil egg shells, but certainly very exciting (and convenient!) to find belemnites and other marine fauna so close by! 3 ...How to Philosophize with a Hammer Link to comment Share on other sites More sharing options...

I'm sure the gravel came from a quarry in the south of England. We can pretty much pick up a handful of stones and find something interesting. Great site and thanks for the quick replies.

TqB Posted May 17, 2020 Share Posted May 17, 2020 It's a sponge in a flint nodule (from the Cretaceous Chalk). Anything strange in flint is quite likely to be a sponge and there are many kinds. Tarquin Link to comment Share on other sites More sharing options...
