Morning,
found these on Newhaven beach yesterday.
Are any of these fossils please ?

Hi Gerry,

You have there an echinoid internal mold preserved in flint. A small part of the original calcite shell remains at the 'top' of the fossil directly beneath the blob-like flint structure that would've been part of the flint nodule that grew around the fossil incorporating the fossil within it. Wave action and erosion has caused much of the delicate 'shell' (technical term is test) to fall away but the shape (and a little detail) of the original fossil remains. Without a scale and a view of certain parts of the fossil it's difficult to assign a specific genus/species but I'd guess that you have an Echinocorys scutata fossil which are fairly common in the soft chalk of Newhaven although finding whole specimens with the test intact can be a little trickier. The fossil probably belongs to the Newhaven Chalk but there are several other chalk formations in the cliffs there and the fossil was not found in-situ so you'll probably never know for certain. Good find! The cliffs between Newhaven and Peacehaven are extremely fossiliferous and you can find some great fossils in some of the boulders that have fallen from the cliffs, though I'd certainly not recommend going anywhere near the towering cliffs!
The other two pictures you've posted are also flint , but not fossils unfortunately. Flint is very commonly mistook for fossils, especially when 'banded' such as the grey flint specimen on the left in you photo.
