looking for some help with some rocks ive found! this is from a rocky beach that is lush with fossils, mostly like the ones in the first picture. i know what those are, but the other two have me super excited. the cracked egg looking rock looks like it could be split and may have something inside - but its the sandstone striated beast im the most interested in. could it be a bed of tiny ammonites? might it also have something worth splitting it for? should i get these bad boys cracked open??
