I found these whilst poking around shanklin beach on the isle of wight i split the two down the middle and found one thing that looks like bone with reptile looking skin closely attached, the other appears to be a large tooth but i have no idea if it is anything.
All I can see by way of fossils is something that might be a burrow (filled with sediment, as they usually are).
By way of reptilian skin, I can see one small patch showing some white sand grains in a dark matrix; not skin.
For future reference, viewers will be more inclined to look at your photos if you downsize them.
Yes, having them full-res helps when looking at details, but you might be surprised how much detail can be retained despite downsizing (by reducing resolution and/or increasing compression). Many photos uploaded to NaturePlus have file sizes 10 to 100 times smaller. There are many image resizers out there.
