I found this small black stone on Brook Bay, Isle of Wight. It's almost black and has an interesting smooth groove down the middle, with two rough warn patches on either side which appear to expose a honeycombed texture. I don't know a lot about this sort of thing, but I have read online that dinosaur bones can be found along there and sometimes look similar, so I thought I'd ask the professionals!
Can you tell if I've found anything interesting or have I just found a boring old rock? I've attatched pictures!
Thank you guys!
Superficially, it has some resemblence to fossil bone (which is often black).
But your photo shows it is composed of angular particles - grains of sand, so it is probably a piece of sandstone. The orange-brown-black colouration suggests if might be ferruginous sandstone, which could also be called ironstone.
The spongy texture is probably due to the minerals forming the cement (between the grains of sand) partially dissolving.
The tricky thing with that explanation is that there appears to be a distinct rind, though which the spongy interior is visible only erosion/breakage has exposed it.
To be sure, a microscopic examination would be needed.
However, there is a chance that I am mis-seeing the photo, and that it is dinosaur bone; dino bones are certainly known from the bay.
Hi Glenn, welcome to Nature Plus.
A great image (wish mine was as good) it's difficult to tell what your specimen is without it in my hand but I remember seeing a lot of very similar material at Horse Shoe point near Shanklin, unfortunately non of it was Dino bone.
Although it is hard to find you can collect Dino bone in many places on the south coast of the IW, Yarvaland is good given the right beach conditions.
Thanks for your answer! I took that photo from my iPhone, it must have just been good light!
Thank you very much for your answers!
I'm actually very envious of your ability to tell from a glance that it's just sandstone. Next time I'm amateur fossil hunting, I will try not to bring back another Sandstonosaurus!
Go for it!
If there is such a thing as a horta (it's a Star Trek thing), a Sandstonosaurus has to be on the cards!
It was only trying to protect it's eggs! That Horta was so misunderstood.
