Crazyhen Posted October 19, 2019 Share Posted October 19, 2019 Any idea if this tooth belongs to dinosaur or Sabre-toothed tiger? It is said to be found from Ganzhou of Jiangxi in China. Link to comment Share on other sites More sharing options...
Troodon Posted October 19, 2019 Share Posted October 19, 2019 The shape of the tooth and denticles do not appear dinosaurian. Has more of the canine look of a tiger but not sure. 2 Link to comment Share on other sites More sharing options...
Nimravis Posted October 19, 2019 Share Posted October 19, 2019 Looking at the last picture, I say Saber Tooth canine, the tip could be concealed in the matrix, but I hardly doubt it. 2 Link to comment Share on other sites More sharing options...

Mark Kmiecik Posted October 19, 2019 Share Posted October 19, 2019 I thought Smilodon was only found in the Americas? Edit: Oops -- Machairodus -- didn't see that. Appears about the right length to width ratio. 1 Mark. Fossil hunting is easy -- they don't run away when you shoot at them! Link to comment Share on other sites More sharing options...

How can you tell the tip is in the matrix. Do you have x-ray photo vision? I'm not determining the length. I'm comparing l/w ratios of Smilodon vs Machairodus, based on the taper evident in the specimen shown. 1 Mark. Fossil hunting is easy -- they don't run away when you shoot at them!

TyBoy Posted October 19, 2019 Share Posted October 19, 2019 No xray required... the tip might not be in the matrix, we dont know, hence my point in trying to determine length its it impossible off of a photo. 1 Link to comment Share on other sites More sharing options...

Not determining the length. Looking at the length to width ratio of the visible portion and comparing it to that of two species. In other words, does the visible part appear to have the same taper as one species or the other? Shorter teeth will have a more radical taper than longer teeth. The tooth of a Smilodon is considerably longer than of a Machairodus and therefore the width variation at a given length from any point will yield a ratio that is different between the two species. 3 Mark.

Crazyhen Posted October 28, 2019 Author Share Posted October 28, 2019 Photos of higher resolution attached. I have further checked, there is no record of Machairodus in Jiangxi. So, if it’s really Machairodus, it’s a new locality. Or it is not Machairodus. Link to comment Share on other sites More sharing options...
