Measuring a theropod footprint

Finding the dinosaur tracks is always exciting. Especially if they are from very large animals. This theropod seems to have left the print of its true heel (the metatarsals) as well. This footprint without the metatarsals impression and with the missing tip of the toe # III (the broken off rock) taken into account, according to the shape and the relative dimensions of the other smaller prints on this site (Pogledalo promontory of the Main Brijun island, Istria, Croatia). measured about 60-65 cm in length: This translates into a theropod that was about 9-10 meters long. It is a left foot impression. The trackway is from the Early Cretaceous, Barremian age. Some 125 million years old.

The tracksite has been described in the paper free to download.

The new sensational Cretaceous bird (repost)

Although, I know that many birds and dinosaur-birds lived alongside dinosaurs some 125 million years ago, during the Early Cretaceous, I always get surprised by the new discoveries. How come the ancient birds looked so advanced and modern as early as  that?
The newly described Chinese fossil bird Hongshanornis longicresta wouldn't make you turn your head if it flew by you. It seemed so common. Only a closer look, a very close look, would reveal that it had tiny teeth in the front of its beak and claws on it's wings.
A couple of years ago I was engaged in a project of producing and mounting a theropod  sculpture on the famous and rich Barremian track site on the Main Brijun island in Croatia. The tracks are roughly of the same age as the Chinese Jehol bird fossil. There are theropod tracks of various sizes at the site. The largest footprints measure about 60-65 cm in length. I have also noticed a large crock footprint, iguanodontoid tracks and possibly a pterosaur footprint there.

The sculpture at the Main Brijun Barremian tracksite by the the team of artists: sculptors Stjepan Gracan and Bozica Dea Matasic; painting and mounting by painter Zlatko Kauzlaric Atac; cconsulting and preliminary drawings by Berislav Krzic. It took almost 3 years for the sculpture to be produced and mounted at the track site in 2012:
