Dear Natural History Museum,
My name is Joshua and I am 7 years old. I live in Peterborough. I like fossil hunting and I have found lots of fossils from the Oxford clay. Dad and me have found out lots in books and the on the internet. I took some of my fossils to the Natural History Road Show in Peterborough the lady from the Natural History Museum said I should get in touch.
We have lots of marine reptile teeth maurenosaurus, cryptoclydus and metoirychus.
We also have a very big tooth with fat lines on it. But I have got some bits of jaws we want to show you and two teeth that are not like marine reptiles and we think we have a turtle shell, and a bone which is very delicate and it has crystals inside.
I have taken some photos to show you. Can you help us find out what they are? Can I bring them into show you?
picture 1 looks like a fish bone, maybe a tendon, the teeth look like ichthyosaur teeth, appart from that tooth which is in in a jaw which looks too small to be an ichthyosaur jaw so it could be a fish jaw, and them shell things on the rocks Are ammonites. Also the bone that I think is a fish bone would probably glue together perfectly with a bit of super glue. Also if you want to polish your fossils you could use wood varnish. I use it all the time and my fossils look really good when polished.
I hope this was helpful
Also, there is something else I forgot to tell you about them: they are jurassic in age (around 190 million years old). Where I live, the fossils are carboniferous in age and they are 320 million years old. That is way before the dinosaurs, but I still find loads of petrefied wood pieces. The oxford clay is the age of the dinosaurs, but they are all fossils from the sea. Also, a place I suggest to go fossil hunting is abbey wood in London. I have never been there but apparently it has loaded of fossil shark teeth there.
I am a lot older than you but when i was about 7 my dad brought me some fossils home from a 'pipe line' he was digging and the interest/obsession has stayed with me all my life, i have even passed it onto my 5 son's.
Well done to your dad ! as well as mine.
