A juvenile and an adult hominin (8'8" tall) were proven by bone bone and tooth analysis. Report is found here. On page 74 in conclusion; "The Taphophonic evidence strongly suggests that the taxa responsible for the forensic dental avulsion attributed injury evidence are a currently unclassified form of hominin."
These bones and teeth showed signs of tooth marks on them in the Mt. St. Helen's area. Footprints 16 x 7 x 4.5 at the heel (step length of 72 and stride 144 inches). We humans have average 10.76 inches x 3.6 inches and step length of 31.10 inches and stride of 62.20 inches.
(Must listen - especially around 6:30 minute mark onward)
This is beyond exciting news and the implications are enormous!
