nchazarra Posted April 6, 2010 Share Posted April 6, 2010 Last Sunday I found this bird track in very shallow marine sediments Miocene in age. I will go back in a month and see if there are more tracks or any other biological activity on these sediments!. Link to comment Share on other sites More sharing options...

In formal logic, a contradiction is the signal of defeat: but in the evolution of real knowledge, it marks the first step in progress toward victory.

Auspex Posted April 6, 2010 Share Posted April 6, 2010 ...I will go back in a month and see if there are more tracks... Yes, please do! If I interpret the print correctly, the hind toe is too long in proportion to the others. I have marked your image to show what I mean (the lines are the length I would expect to see the front toes): As with all tracks in mud, it is possible that the other digits failed to imprint on this one, or that the impression of the hind toe is elongated by dragging. If there are other tracks, they could help me see this as a for-sure bird track.

TourmalineGuy Posted April 6, 2010 Share Posted April 6, 2010 (edited) Auspex, What if the hind toe mark is only the short section, not the including the "blob" at the end? Like this: It looks like the front middle mark is not fully there, too so I put the ? and dash. Would that make more sense for a bird print? Roddy Edit: Oh yeah, really cool find!

It looks like the front middle mark is not fully there... Would that make more sense for a bird print? Roddy Yup, that would be the ticket. The "overlong" hind-toe print could be because of a dragmark or something like it.

Shamalama Posted April 6, 2010 Share Posted April 6, 2010 Neat print. Maybe it was a backwards walking bird? -Dave __________________________________________________ Geologists on the whole are inconsistent drivers.
