|Overview of boulderful of mystery fossils; each lump several cm across.|
The initial cry of 'I've found a dinosaur' was followed by thoughts of 'yeah, right' and then 'er, well, actually...' and so a more careful look was needed. Now, I'm no palaeontologist, but dark pitted lumps in a pale matrix shout 'fossil bone' at me. Or maybe coral... The structure was pitted and compared favourably with a chunk of brontosaurus I've got on the shelf (the small holes and channels were visible, but I wasn't able to get a photo where they showed up clearly), but most interesting were the smaller (a few cm) volcano-like structures protruding from the boulder in a few places among the lumps of maybe-bone.

A bit of research online and even in books started nudging my thoughts away from coral and towards scutes (rectangular-ish armoured skin plates) from a crocodilian of some sort. Many images from these sources appear pitted (not unlike a crumpet in texture) but others are similar to the two photos above. Also, a well-known palaeontologist-blogger suggested the same, so I'm feeling cautiously vindicated at present - and of course, there could be coral, and other things, in the boulder too. However, thoughts on this are most welcome, and there will be an update if anything changes. Until then, my wife's feeling very pleased with herself...
