New tracks

Yesterday afternoon, I was walking along the outcrop near Pula, that I had visited only once before while searching for tracks. This time I had a bit more luck. I have found a couple of large theropod footprints in a straight line, but not as a complete sequence. The third, middle footprint was missing because it was covered with the rock layers. Although the state of preservation is rather poor, it seems both prints are from the left foot and the missing one is the right foot. The animal was walking fast with a rather long gait. The length of the footprint is about 45 cm.

 The last image above is my interpretative footprint outline.

 The outcrop has some interesting geological features. Gypsum crystals are quite abundant.

Here is another track site (probably sauropods) about a 100 meters further down the beach.

 Gypsum crystals are abundant and are glittering in the sun.


Many of the rocks are broken in a way as if they have been cut by a man. Which, of course, is not the case here.

Good old Triceratops


Triceratops is certainly among the most popular dinosaurs. Here is my restoration from 1990/91:


... and here is my latest restoration (January 2015) of a juvenile specimen:



One of the ceratopsians with very distinguished bone frill was Pentaceratops (my restoration from 1990)

 Torosaurus with young (2001). There are some theories claiming that Torosaurus is in fact an ontogeny stage of Triceratops.



The main predator feeding on Triceratops was Tyrannosaurus rex (1993)

Sophie the stegosaur

I am back from London. Of course, one of the first things I wanted to see was the new stegosaur mount at the NHM. Here is one of the photographs my daughter Masa took.

More on Pula ankylosaurs

I have discovered the second site containing ankylosaur tracks (dinoturbation) near Pula about a year after the first one, which is about a kilometre away. It is interesting, but this time I thought I was looking at the single theropod footprint. Yet, it didn't seem right. It didn't look like a typical theropod footprint. Nearby was the second impression, only convex (infilling). The pace angle was too wide for a theropod. I have also noticed there were in fact 5 toe impressions. The print was obviously left by a quadrupedal animal: a large ankylosaur. Later, I have discovered more foot impressions of the same animal, or the animal of the same size.

The red outline of the best preserved impressions in the ankylosaur trackway.


Another foot impression ( right hind foot - pes) of the large Sauropelta-like dinosaur on the same outcrop. This one is not part of the trackway above (red outline is my interpretation).
