Hello, you have two different types there - the long one is 'horse' and the other 'cattle' but it is rather difficult to tell whether these are really ice age wild animals or more recent domestic ones, perhaps archaeological - there is a Roman site there and a Saxon shore fort. Teeth last a long time even after all the jaw bone has completely gone.
Hello, thanks for your help on the identification. They were found very close to each other in the mud, so it could have been near an area where the carcasses were discarded - if they are archaeological. Or they were two very unfortunate modern-day animals that got stuck.
