Found West Dorset beach, Jurassic Coast, cycad?

We found this (as shown, we haven't cleaned it) on West beach, West Bay, Dorset the other day. We've had lots of cliff falls lately and sea is very rough so assume it's out of the cliffs. It was washed up, found at low tide, not directly near a cliff. It's very hard, reasonable weight, assume it's fossilised. Any ideas as to ID? First pic shows it still damp, it's now dried to paler colour.

    Hi,

    this looks like a recent Pine cone to me - its obviously been in the sea for a while and washing up and down the beach has probably worn the cone scales down to give the smoother appearance here. From the size and asymmetric shape I suspect it's Pinus radiata (Monterey Pine) which is commonly grown along the Dorset coast.

    Hi,

    I'll check yo see that I am right but it looks like fossilized dung or a fossilized pinecone. I'm sure an expert will coreckt me if I am wrong.

    Seasky,

    Wow - that's a nice one!

     

    To test if it is recent or a fossil, tell us what it sounds like when you hit it with another stone (gently). If it 'rings' or sounds hard, it is a fossil. If not sure, determine its density by weighing it and calculating its volume by water displacement. Rock should be around 2.5g/cc.

     

    Probably best to widen the search to the Cycadophytes to start with, to include Cycad relatives such as Bennettitales. I would not rule out conifers

     

    If you don't get an answer here, I have a feeling Neville Hollingworth might be able to cast a useful opinion
