Weights are subject to change.

Shoulder height were determined by measuring full skeleton photos or reading literature data.

The largest A. simus is from a 723 mm femur.
The largest A. angustidens is from a 620 mm humerus.
The largest U. m. tyrannus is from a 485 mm ulna.
The largest cave bear (U. ingressus) is from a 485 mm basal length skull.
The largest A. africanus is from a fragmented femur estimated to be around 530 mm in length. 
The largest polar bear (U. maritimus) I took from Derocher and Wiig (2002) and rounded up 10 kg.

Yes, I edited A. angustidens to look like a steroidal spectacled bear. Reply
