For those unable to see beyond Africa as the "human cradle", these tracks present a considerable challenge, and it has not been easy to get the discovery published. Some have even questioned whether the observed features are footprints at all. However, collectively, the researchers behind this study have published over 400 papers on tracks, so we are pretty confidence we know what they are.
AbstractWe describe late Miocene tetrapod footprints (tracks) from the Trachilos locality in western Crete (Greece), which show hominin-like characteristics. They occur in an emergent horizon within an otherwise marginal marine succession of Messinian age (latest Miocene), dated to approximately 5.7 Ma (million years), just prior to the Messinian Salinity Crisis. The tracks indicate that the trackmaker lacked claws, and was bipedal, plantigrade, pentadactyl and strongly entaxonic. The impression of the large and non-divergent first digit (hallux) has a narrow neck and bulbous asymmetrical distal pad. The lateral digit impressions become progressively smaller so that the digital region as a whole is strongly asymmetrical. A large, rounded ball impression is associated with the hallux.Morphometric analysis shows the footprints to have outlines that are distinct from modern non-hominin primates and resemble those of hominins. The interpretation of these footprints is potentially controversial. The print morphology suggests that the trackmaker was a basal member of the clade Hominini, but as Crete is some distance outside the known geographical range of pre-Pleistocene hominins we must also entertain the possibility that they represent a hitherto unknown late Miocene primate that convergently evolved human-like foot anatomy.
No, Crete was connected by a land bridge at the time.* This was in the Messinian period, so not much water in the Med.*ETA: Well, I think it was. Either that or the buggers were bloody good swimmers.
I'll leave it to the experts I will accept the published material over the opinions of some people on an internet discussion group.
On the other hand...Spoiler (click to show/hide)I'm not entirely convinced those are tracks. Perhaps if someone was walking in an irregular pattern, looking for safe footing, I don't know.
By a teacher who intended to sell them. The rest of the site's been buried to prevent further vandalism.
