Two honking great big Gryphaea (devil's toenail fossils).

(Edit: hello to all from Whitby Sea Anglers. A longer welcome here.) Another unpromising day on the beach, 30 mph face-freezing SE winds making the prospect of wet-handed naturalizing uninviting:
The beach is in its winter clothes: the incessant gales have scoured away the sand that makes the place so inviting to the summer hordes. As a result, things not usually seen by visitors are on display: shingle, rocks, bits of shipwreck and fossils. Here an ammonite counterpart that any sharp-eyed young fossiler would fall on delightedly...

 
And here, in the centre, a Gryphaea. The scouring tides have meant that a lots of these Jurassic oysters have come to light: they're usually a rare find of Runswick Bay beach.
  
However, a little further down the beach, find of the day. Two big Gryphaea, which appear to have died together. Overwhelmed by a mudslide, died of some unknown Gryphaeaic ailment or eaten, part digested and vomited back by a small icthyosaur? Who knows. But these two specimens are fine additions to the collection, photographed here in situ and compared to the other, more usual-sized Gryphaea that have been found as a result of this 'spring' weather and tides:

Great to see you writing regularly about Runswick, I enjoy reading all the fossil posts too. I'm there every other week in the summer kayak fishing, it's really a special place. Quite we come ashore when the fishing's slow, and have a little hunt for fossils with our sandwiches. Great spot!

Steve checked it out, I think you might be right but it needs more careful inspection. Hope to see you soon.

Hi,
Yesterday at Runswick Bay my older son found a small grey stony nodule in the loose rocks, a bit bigger than a golf ball but smaller than a tennis ball. Do you think it could be interesting? We can try sending a photo later.
