hi ,after a great time on the beach we found a large amount of different items ,we found quite a few what we believe to be devils toenails and a lot of ammonites .the first 2 pictures we have posted are of a strange rock with the markings you see are quite raised it is almost identical front and back.we wondered if anyone had any ideas .
the next picture a beautiful little shell we wondered how old this maybe .and the last 2 pictures are front and back and wondered what these could be .thank you tabfish for telling us of this place had a fantastic day .thanks beckie,jake
Hello Beckie and Jake.
Some fantastic finds! Well done.
I love Marske but the conditions have to be good for collecting just like the Holderness coast.
If the sand is in then forget it, but if you can see rocks — go for it.
Your first two images are of a Sea lilly stem (crinoid) nice find and would look good with a bit of prep.
The shell is probably Jurassic (200myo) hard to tell what it is but it looks to be a bivalve.
Last two images are hard to tell exactly what the specimen is, but I would take a guess at a mineral infill between the matrix as there is no sighn of anchant life.
I think the narrow one in DSC_1387 (1).jpg could be a crinoid arm.
Here's a photo showing a crinoid calyx, arms and (smaller) pinnules
DSC_1365.jpg is a gastropod, a bit like this (much more recent) turbinid one
I agree: the last two are probably not fossil; they are probably just veins which, being a bit harder than the adjacent rock, have come to stand proud during weathering.
hi thankyou tabfish and Mike for your replies.Thankyou for the links Mike its amazing how the criniod arm something so delicate could become fossilized.we have more pictures but need to get them on my computer .beckie,Jake ,:)
