Hello, found these down on from lulworth cove in dorset, area has a "fossil forest" which is why we believe these to be wood! The black one is too light to be rock but has a shiny appearance 

Just to add these weren't taken from the fossil forest, they were found further along the coast!!

Also any advice on how to clean them up? 

Thank you 

Saskia

Hello Saskia and welcome to the forum. I am not certain from your photos that they are all wood because Cacite can form fibrous lumps called 'beef'. I would need to see the detail using a hand lens or microscope.
Whatever you have needs to have any salt from the sea water removed as this can break up the specimen when dry. Soak them in a bucket of tap water for a week or so changing the water every couple of days and giving them a scrub with a toothbrush to remove any loose particles. Allow to dry out naturally. This should then be all that is needed unless there is evidence of Iron Pyrites (crystals,within the structure of the rocks. If you see a whitish powder forming then this is Pyrite decay and will need special treatment. I hope this helps!

Thank you! Will give it a go and see what (if anything) comes of it 🙂

Saskia, just a thought, but you may be interested, when you've sorted the cleaning, IDing etc, you might want to cut and polish the section(s)? Contact me if you do.
