After a bit of an unplanned road-trip we ended up at Bridlington North Beach about 1 hour after high tide. Killed some time grabbing a bite to eat and playing on the sands until we could see that the water was well away from the cliff base to the North. First ever time looking for chalk fossils so we wasn't sure what to look out for, or what to do when we found them, so probably missed alot.
However we did find these while walking from Bridlington North Beach to the steps at Sewerby Hall. (A nice easy 1 and half mile walk suitable for kids. Just make sure to leave on a falling tide. There are a fair few steps to reach the top of the cliff at Sewerby Hall but they are well maintained and not overly taxing. As a bonus there is also a pub right opposite which has a kids play area and serves food as well as drinks.) I am assuming they are all 'sponges' 1 2 3 The 'Fossil' appears to pass right through the chalk with the wide end being in line with the thin end that looks like a black line on the side of the chalk in the first picture. A close up of the thin end is on the last picture.

Yes, the first ones are sponges, maybe
Scytalia sp. And a good speciment at that. The nice thing about the Sewerby Sponge Bed, for such it is, is that the sponges are silica and the chalk is calcium carbonate, so you can dissolve them out with dilute HCl or similar ... __________________ MFM
