A theropod track from Solaris outcrop
"The field work in the late Albian track site of the Solaris Campground near Cervera/Červar (Torre/Tar municipality, Istria, Croatia) was undertaken during the years 1995-96 thanks to a grant of The Dinosaur Society and the collaboration of the local authorities. The field work at the site has been described in DALLA VECCHIA (1996). A description of the site before the cleaning of the main footprint-bearing surface and its detailed mapping and description can be seen in DALLA VECCHIA (1994). The detailed description has been published by DALLA VECCHIA et al. (2000)."
What's interesting about the Solaris track sites is that they are represented with relatively small dinosaur tracks. Dalla Vecchia speculates that the dinosaurs were of a diminutive size due to their habitat. They lived isolated on an island, whose resources couldn't provide for the "full-size" large dinosaurs that inhabited the mainlands. On the other hand, although roughly from the same age and just some 40-50km away, dinosaur tracks from Pula beaches are of many size classes, the biggest of which are among the world record breakers.
In the image below, you can see one of small theropod tracks from the Solaris beach. Red outline is my interpretation. This one wasn't described in any paper, yet.
There is probably more than one footprint in this image, but I have outlined only the best one.
