Dino9876 Posted March 26, 2020 Share Posted March 26, 2020 Hello, I am currently re-sorting my collection and this brings up some questions about some modern shark teeth. For example, I found two teeth of this appearance. At first glance, I would suspect a Carcharhinus species (like C. falcifromis, but the teeth look different) , but I don't know which. Unfortunately, I don't find any comparable teeth in the Internet. Even if this isn't a fossil this time, I hope that you can help me again. The tooth is 1,3cm (0,51") in size and from the philippines. Best regards from Germany!

I don’t think you will be able to identify the species. It is an upper posterior tooth. Several species have similar teeth in that position. 5 Link to comment Share on other sites More sharing options...

Al Dente Posted March 26, 2020 Share Posted March 26, 2020 Carcharhinus teeth are easier to identify if you have the whole jaw, then you can use dental formulas (tooth counts) to narrow down to species level. 3 Link to comment Share on other sites More sharing options...
