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.
After writing on the Trinil mandibles, I don't think it is. The specimen is between 70-90 kg but clearly an adult. The other Trinil specimens I found to be around 200 kg. Maybe the Trinil femur could be of a small female, but femur's anatomy doesn't fit a tigers.
The shaft is proportionately very thick but the extremities are thin. The proximal:distal ratio is larger than what is found in tigers and even in the Ngandong femur. The head of the proximal femur is also thinner than what is in tigers, or any large modern pantherine for that matter. Brongersma also noticed how the cross sectional shape of the shaft differed from that of the island tiger femurs.
The other Ngandong femur vK labeled as Panthera sp., meaning unidentified, does not exactly match the Trinil femur either but seems closer. At the moment, I am leaning toward the Trinil femurs being some form of primitive leopard rather than tiger.
