FOSSIL UPLOAD
First, make sure you have a myFOSSIL account, this is required to upload your fossil information. If you are interested in seeing if your fossil can be used for research purposes, please follow through the following steps. They walk you through the information needed and why it is helpful for other scientists to use it for research questions. Even if the information you have on your fossil is not enough to be used for research purposes it will still benefit the community through educational means and help others identify their fossils. Specimens that have sufficient information will be uploaded to iDigBio and GBIF (Global Biodiversity Information Facility) for public accessibility.
If you have already gone through the stepwise process that explains each piece of data please click through to a summary tab where you can enter in your specimen data on a single page.

2X2 cm, mentioned in the dimensions. @bill-heim
Hello @drsukhendu-mukhopadhyay , you will still need to add a scalebar to your photos for us to mark it as research grade. I think the identification shouldn’t go beyond the genus Carcharhinus for this specimen. There are too many Carcharhinus species with similar teeth to be certain.
I disagree, I think it is Glyphis. It doesn’t match well for other Carcharhinids but does match for Glyphis with the serrations and the overall shape. Glyphis is found in that area. It fits well for an upper A3 tooth. I have a jaw(s) of each major Carcharhinus species that have broad teeth and it doesn’t fit well for any of them. In his…[Read more]
The Speartooth Shark has so far only been recorded in tidal rivers and estuaries within the Northern Territory and Queensland. Within the Northern Territory the Speartooth Shark has been recorded in the Adelaide River, South, East and West Alligator Rivers, Murganella Creek and Marrakai Creek. In Queensland the Speartooth Shark has been found in…[Read more]
The Copper shark and the Seven-Gill shark are only known from the Pacific. We collect multiple fossils of both here on the Atlantic coast of the US. Present known distribution records (which are incomplete) has less relevance to the fossil record.
