A trip to Lisbon

Here are some photographs from the trip, placed randomly.

The new sensational Cretaceous bird

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:

Here is my restoration of the ancient bird Hongshanornis longicresta:

Forbidden planet's Monster from the ID

  I keep watching Forbidden planet movie from time to time. It was so good, so ahead of its time in so many ways: from the music score to the design. One of my favourite scenes is when the captain and the doctor were speculating about the shape of the monster, deducting from cast of its footprint. It is quite similar to the real task when paleontologists are trying to figure out the characteristics and features of extinct animals who left only their petrified tracks in the rock. I search for the ancient tracks on the Adriatic coast and it is a lot of research and fun.

It is also amusing that some species of dinosaurs had claws, not unlike the one from the movie, but on their three-fingered hands. Check out the cast of the finger claw of the allosaurid theropod  Saurophaganax here :

My drawings of the fossil bones of some theropod hands. Above is Megaraptor left hand (manus) and below is Allosaurus left hand:

Please, note that in life, the claw would be covered with a keratinous sheath - talon (like our nails) which would make it considerably longer.
