Split the PaleoDB sloth HE into its own page & merged in PaleoDB water bear HE. After reindex some sloth media have moved to the new concept, but still get sloths in media collection. Reindex again. Finally managed to merge in the correct PaleoDB HE. Reindex again. Weeks later, this media collection looks clean. Hallelujah! -- July 2014. Paleodb sloth HE is back in, possibly as a result of the pbdb reharvest. Splitting again.
