Comparing a modern Amur tiger with a Bengal tiger of any time, is like to compare a Football player (the real one, A.K.A. Soccer) and a wrestler, both of the same height.
Both are athletes but the Amur tigers are slim and long, while Bengals are very robust in comparison. Check that males of over 200 kg reach 130 cm in chest girth, while a Bengal of 260 kg have chest girths of 140 cm and more. However, old Amur tigers were larger, which chest of 150 cm, just like the largest Bengal tigers.
Interesting, if we use the chest girth-weight equation in Kerley et al. (2005), a chest girth of 140 cm will produce a weight of about 217 kg, and one of 150 cm, a figure of 242 cm. On the Bengal side, the results will be probably 270 and more.
This is the equation: y=2.5612x - 141.73 ---- r2=0.9165. "x" is the chest girth of the Amur tigers.
At the end, is the same modern known mantra: modern Amur tigers are thinner, but old ones were of the same caliber.
