I would put this basically the same as Simus.

For Pristinus and Floridanus, there is very little data on our threads to get an average, but we do have weight ranges.

For Pristinus and Floridanus, there is very little data on our threads to get an average, but we do have weight ranges. ( 330 to 660 pounds ). I would estimate an average of roughly 500 pounds. Hopefully, we will discover new data soon. |

Arctotherium angustidens:
average weight - 1500 pounds.
max weight - 2400 pounds. Could you post the citation for just 1500 pounds (680kg)? Me and undertaker went over the topic sometime back on discord and the average figure that undertaker calculated was ~843kg, the estimates coming from christiansen & harris' publication based off femur and humerus width. |

Continued: INTRODUCTION
With an average body mass estimated at 700–800 kg (Christiansen, 1999b), the enigmatic ‘short-faced’ and ‘long-legged’ bear Arctodus simus (Cope, 1879) (Mammalia: Carnivora: Ursidae: Tremarctinae) was the largest terrestrial carnivoran that ever existed in North America, playing a pivotal role in the Pleistocene ecosystems (Fig. 1A). As a matter of fact, remains of Arctodus have been recovered from more than 100 North American localities, spanning the middle Irvingtonian through the Rancholabrean (Richards and Turnbull, 1995) and becoming extinct with most of the megafauna after the last glacial maximum (Guthrie, 2006), at ≤11,400 BP (Gillette and Madsen, 1992).
Quote: With an average body mass estimated at from 1,543.24 pounds to 1,763.70 pounds.
Quote: In any case, our results provide a coherent picture of A. simus as the largest North American carnivore during the Quaternary.

843 kilograms is equal to 1,858.50 pounds.

*Since 'Taker and nocap went into this, we can up this average to 1,860 pounds. This topic remains open for change according to findings.

1,500 lbs is still huge for a prehistoric bear. Largest modern day bears average only 1100 lbs.

A prehistoric bear weighting around 750kg is a very large bear, but not even close to the largest specimens.
