Tooth found in my garden in Korea

[Octave]

Dear all

 

thank you for your passionate discussions.

 

yesterday we’ve found this what appear a tooth.

 

Precambrian soil with a marine sediment. We are very interested to know what we discovered.

 

it’s seems not mineralized and I thought that we found a dog teeth…. But it seems quite big.

 

thank you for your opinion
