Found this lump in the landslip below Blackgang Chine, Isle of Wight. It looked black when damp but has dried grey and so looks like it came from the Gault Clay but there is also Greensand Formation above. Also has some rusty colours on the inside where it looks like it has split in half from a larger cylindrical piece. I guess it’s just a geological formation, but the fibrous looking texture on the surface made me think of teeth and horns. It also appears to have had a cylindrical hollow running through it when complete. Thoughts much appreciated

Found this little flint nodule in the stream below Blackgang Chine, halfway down the coastal landslip there. It has very distinct little pimples in a conical hollow that finishes in a flat surface. It looks very reminiscent of Echinoids, but different to any I’ve seen before. I believe the local strata are gault clay topped with greensand formation. Any ideas? Cheers!

Hello. Found this nodule yesterday halfway down the landslip facing the sea in front of Blackgang, IoW. I cracked it open and was surprised to find these very distinct fibres running through. I cracked the bigger lump open this morning revealing a pyrite shaft in the centre. I believe the local strata are greensand formation above gault clay. Since the earth is so churned up down there, it could have come from either. Any ideas? Cheers!
