Marazion beach combing - fossils - part two 🦈

So here we are at Marazion and there is St Michael's Mount .
To the right you can see Penzance in the distance . When the tide is out , and I mean a very long way out , there can be seen tree stumps and roots which are the the remains of a 6,000 year old forest .
To the right of St Michael's Mount we are looking towards beautiful Marazion village and the causeway where you can walk out to the Mount or catch a boat if the tide is in .
I continue on with my beach combing ...
....and then my eyes were drawn to this !
Yes , I brought it home with me ! Now , If I had found this up on the Isle of Wight ,(and could this have washed all the way down here from the Isle of Wight ?) I can see bone capillaries . I would have thought Cretaceous-land dinosaur spike, horn , scale or tooth ...polacanthus maybe ....but Marazion ? I look up Marazion and find that there is an area of it that is Late Devonian . I know the Jurassic period very well from fossil hunting up in Charmouth and the Cretaceous with it's land dinosaurs at the Isle of Wight and we have had some amazing finds there , but , I really don't know anything about the Devonian period .
I did some research and found out that the Late Devonian Period is also known as "The Age of Fishes " So now I'm thinking ...😱 🦈 Dunkleosteus 🦈 tooth . This beast had teeth that grew out of it's jaw bones and self sharpened them as it opened and closed it's jaws . I remembered that there was a small geological museum in Penzance , but when I tried to contact them about maybe coming to visit , I was told it had closed down and no one seemed to know where the collection had been moved to .
It's all very exciting and I can't wait to get back down on the beach and see what else I can find ! By the way , our own local beach , Poldhu , also has remains of 6,000 year old forest when the tide is a very long way out, it is very soft and peat like and there is also an area of Late Devonian . I found a nice fossil piece of (we think) a pine branch . It was just lying on the beach . 🦈That's all fer now folks ! I should be writing Christmas cards ...lol ! 🦈
