Theropods of Pula

 

Theropods were everywhere

From the Pula mega track site. Early Cretaceous (Late Albian)

I can see a left pes print of a big theropod. Note the middle toe (#3) curving slightly towards the right (the mid-line).

Veliki pernati teropod

Yutyrannus

Tijekom donje krede je došlo do određenog razdoblja hladnije klime, unatoč činjenici da je ugljikovog dioksida u atmosferi bilo čak deset puta nego danas. 

Je li to bio razlog da su se veliki teropodi "odjenuli" u proto-perje?

Osam-metarski kineski tiranozaurid je bio jedan od tih. Nakon okončanja hladnog perioda, klima se opet zagrijala. Da li su onda veliki teropodi izgubili perje? Ili im je to ostalo?

 

Another strange body impression

The Pula mega track site

A peculiar case of the probable reptilian body print from EK mega track site in Pula. Candidates: croc, gator, monitor lizard, chamsposaurid. Seemingly very large oval scales on the belly. It appears it had 5 toes on legs - (croc has 4)

The photo of the impression in situ and my interpretation:
