I was at the event. Killed several types of ape-creatures. After about an hour, the zoologist indicated that he was certain that the archeological party was devoured by the apes and that he had information to record. I was kicked from the server right as it was ending and could not re-log. My son was able to maintain his connection even after zoologist left. There were no more ape sightings after the zoologist left. From the rare collector's forum, there were apparently 4 different drops that could be looted, a bent shovel, broken pickaxe, bloodied bedroll, and one other. 5 of each dropped apparently.
