Giga-Paleontology (Carnegie Mellon)
Two members of Carnegie Mellon University’s Fine Outreach for Science Fellows
program used the GigaPan-like photomosaic techniques promoted by the program
to study the long trackway of a herd of prehistoric elephants.
The result: New insights into the social behavior of these creatures.
The footprints were left behind some 7 million years ago by at least 13

through mud and left footprints that hardened, were buried, and then re-
exposed by erosion.
Analysis of trackway stride lengths reveals the herd contained a diversity of
sizes — from adults to a young calf — making this the earliest direct
evidence of social structure in prehistoric elephants ever discovered.
“Basically, this is fossilized behavior,” said the lead author, Faysal Bibi.
“This is an absolutely unique site, a really rare opportunity in the fossil
record that lets you see animal behavior in a way you couldn’t otherwise do
with bones or teeth.”
The findings were published Feb. 22 in the journal Biology Letters.
Bibi, of Museum fuer Naturkunde in Berlin, Germany, is a CMU Fine Fellow, as
