There is a world somewhere between reality and fiction. Although ignored by many, it is very real and so are those living in it. This forum is about the natural world. Here, wild animals will be heard and respected. The forum offers a glimpse into an unknown world as well as a room with a view on the present and the future. Anyone able to speak on behalf of those living in the emerald forest and the deep blue sea is invited to join.

This is P4 fossil of Panthera big cat from a outcrop of Songnen Plain, Manchuria, Northeast Asia. The length is 39.6mm and the width is 18.6mm. Because the cave lion, Panthera spelaea, is very small amount in number(even non-existent?) in this area, as far as I know from the public literature which I read, I always thought it belongs to a tiger, Amur tiger, Panthera tigris altaica.
Has anyone modern/prehistoric Amur tiger P4 measurement information/range? Could estimate how size the tiger(body mass or head length) by the tooth fossil?

By the way, I am interest in prehistoric tiger, but unlike cave lion has independent topic, this forum seems to be no topic for prehistoric tigers? Or just i didn't find.....
The largest Amur skull I measured had a P4 of 34 mm and length of 380 mm. This would make the skull length of this specimen no less than 406 mm and probably closer to 420 mm given the positive allometry in skull length and p4 size. Likely a specimen around 300 kg and body length of around 235 cm. Thanks for sharing!
Wow! In my opinion, 380mm is already a very huge individual. But, this specimen's size and mass is more huger and exceeded my expectations.....
For example, a wild male Amur tiger went into Chinese village and shattered car windows on 23th of April this year(23 days ago), he is 2~3 years old with body weight of 225 kg. It looks very robust and strong, and very powerful. By comparison, the 300 kg individual must be spectacular....Really huge prehistoric tiger
