Unusual Crocodile Tooth From Solo River, Java

[-Andy-]

Hi all.

I recently picked up this lovely specimen of a crocodile tooth. It came from the Solo River of Java, and is most likely 200,000 years to 2 million in age.

I am aware that there was more than one attempt to identify the Solo River crocodile fossils in the past, but without any conclusive results. > http://www.thefossilforum.com/index.php?/topic/41300-crocodile-fossil-sangiran-indonesia/

It has two distinctive ridges that run down either ends. My extant Siamese Croc teeth have these ridges too. However, this croc tooth is slightly straighter and more cone-like.

The bottom is quite unusual for a tooth.

Besides C. porosus, are there any other possible species this tooth might belong to? A Google search yielded no results, and i have not located any sellers online who deals in these.

Thank you.
