Abstract

Zahvaljujući drugačijim životnim uvjetima okoliša od onih danas, na području današnjeg
Zagreba, u prošlosti su živjeli Zagrebački kit i mamut, koje je u ovom radu bio zadatak istražiti.
Zagrebački kit (Mesocetus agrami) obitavao je u Panonskome moru koje je kasnije postalo jezero
te je ne kraju i u potpunosti nestalo. Smanjenje saliniteta dovelo je do razvoja endemičnih vrsta i
izumiranja nekih od vrsta poput zagrebačkog kita čiji fosilni ostatci dosežu starost od 13 do 11
milijuna godina. Njegove kosti pronađene su podno Medvednice prilikom eksploatacije vapnenca.
Nešto istočnije, u samom centru grada Zagreba, prilikom kopanja temelja za izgradnju kina Helios
u 20.st. pronađene su kosti izumrlog vunastog mamuta (Mammuthus primigenius) starosti 20 tisuća
godina. Ekstremne hladnoće su bile omogućile mamutu da se nekada nastani ovdje, na današnjem
prostoru Zagreba. Fosilni ostatci obje vrste danas se čuvaju u Hrvatskom prirodoslovnom muzeju
u Zagrebu, a postavljene su replike na mjestima gdje su ti fosili pronađeni. Današnje
visokourbanizirano područje grada Zagreba, nekada je bilo dom raznim vrstama koje se sada
pronalaze kao fosili. S obzirom na stalne promjene u okolišu, zanimljivo je zapitati se što će se
dogoditi s vrstama koje obitavaju u Zagrebu danas.

Abstract (english)

In former different environmental conditions in the area of today’s Zagreb used to live
Zagreb whale and mammoth. Zagreb whale (Mesocetus agrami) lived in the Pannonian sea, which
later became lake and a finally, completely disappeared. Reduced salinity led to development of
endemic species and extinction of some species such as Mesocetus agrami, whose fossil remains
are 13 to 11 million years old. His bones were found under Medvednica, while exploiting of the
limestone. Further to east, in the center of Zagreb, while digging foundations for the cinema Helios
in the 20th century bones of wooly mammoth (Mammuthus primigenius) 20 000 years old were
found. Extreme coldness enabled to mammoth to settle in today’s area of Zagreb. Fossil remains
are kept in Croatian Natural History Museum Zagreb and replicas are being placed in situ where
these fossils were found. Highly urbanized area of the city of Zagreb today, once used to be a home
to species that are today found as fossils. Regarding the constant environmental changes, it is
interesting to ask ourselves what will happen with the contemporary species that inhabit the area
of Zagreb today.
