Guess the tetrapod from the track!
To tell you the truth, at first, while looking at it in situ, I miss interpreted the impression in the photograph below. Only back at home when analysing the photograph on my PC, I have concluded I had been totally wrong in my attribution. It is not a typical footprint example for the particular ichno family. So, this task is really a tough one! A specific diagnostic feature made me change my initial speculation. After that I spotted the other characteristic features, that were not that obvious at the site but which confirmed my thoughts. Although, this diagnostic feature is not always present in the footprints of these dinosaurs, it helped me resolve my dilemma quite a few times.
I'll give you a couple of hints: The site is the Cape Pogledalo on the Main Brijun island (Istria, Croatia), of the Barremian age (early Cretaceous), described in the paper by Dalla Vecchia ; this print was not described in his paper. Note the tip of my shoe (#46) on the right for size. When watched from the side, the track looks like a large shallow bowl. By the icnology standards the footprint is poorly preserved (except one crucial detail).
I challenge the ichnologists to give the answer and the clues in the comments. What kind of animal left this print?
Of course, after some time I'll reveal my interpretation and the diagnostic hot spots.
The usual suspects are: A) theropod, B) sauropod, C) stegosaur, D) ankylosaur, E) iguanodontoid, F) croc, G) pterosaur, H) turtle, I) lizard, J) bird, K) mammal, L) fish
