How large was the Pararhabdodon?
Pararhabdodon
"Pararhabdodon" most likely was a bipedal-quadrupedal herbivore, in the neighborhood of 6 m (19.7 ft) long, fully grown. The dorsal and sacral neural spines were elongate, so the animal would have had a tall back, like other hadrosaurids. Because the material is sparse, more specific conclusions cannot be reached.
Mastodon
Modern reconstructions based on partial and skeletal remains reveal that mastodons were very similar in appearance to elephants and, to a lesser degree, mammoths, though not closely related to either one. Compared to mammoths, mastodons had shorter legs, a longer body and were more heavily muscled, a build similar to that of the current Asian elephants. The average body size of the species "M. americanum" was around in height at the shoulders, corresponding to a large female or a small male; large males were up to in height. Among the largest male specimens, the 35-year-old AMNH 9950 was tall and weighed , while another was tall and weighed .
