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.

Quote:The photographs of the skull of the Belgium zoo Amur tiger were made by the owner of the skull. He's a biologist, but not a photographer. A pro knows how to deal with angles, whereas an amateur doesn't.

The photograph below from an article recently discussed in this thread was made by a pro as well. It shows the skull of a very old captive male Amur tiger from the Hamamatsu zoo. The article was discussed on this thread not so long ago. When you use the scale on the photograph, you'll see that the difference between the real greatest length of the skull (380 mm.) and the length of the skull according to the scale in the photograph is close to zero:

Today, most of us have mobile phones with a camera. The result is a tsunami of photographs and videos. I'm not saying that all photographs are bad, but there's quite a difference between a professional photographer and an amateur. An amateur needs an hour or so to photograph 50 big cat skulls from different angles. A professional needs a day or more. When I was in the Naturalis Natural History Museum in Leiden (Netherlands), a friend photographed all skulls I had measured. He's a professional and needed two days to do it right.

When you publish about skulls and need good photographs, you hire a professional to do it right. Contact any biologist who published about skulls for more information.  

When I visit a museum or someone with a skull collection, the photographs are taken by someone with a mobile phone or a camera. Could be anyone interested. I never hire a professional, because I don't publish. I need photographs to compare skulls of different big cat species from different angles. The board with the scale I used when I started measuring skulls was made by a brother. I thought the scale would help, but the opposite was true in that the photographs often resulted in questions.        

When you still have questions, contact a professional photographer and ask him about the effect of angles and how to remove them. Show him the photographs taken by the biologist in Belgium and the photographs published in the articles discussed in this thread recently.

I just measured the length of Altai's premaxilla by using the first pic that only shows the teeth with 125 mm scale used to measured its canines. Altai's premaxilla is 5 cm.

Then, I look to the second picture that shows the top view of Altai's skull with 125 mm scale. Its premaxilla is still the same at 5 cm. So, your calculation is quite accurate @peter. This is one of the biggest skulls of Amur tiger.


The upper limit for the Amur tiger skull could be re-evaluated as @peter has suggested that there could have other larger Amur skulls than Altai based on his intuition with other giant Amur/Manchurian tigers.
