[ENG] The area around Brbišcica bay is made of carbonate rocks formed hundred million years ago, filled with tiny fossils invisible to the naked eye but also clealy showing lots of fossils of larger organisms. Beside the usual fossilized shells of that time, rudists, also ammonites, fossilized algae and fishes can be seen and an extremely valuable fossil marine reptile was found.
Rudists were reef-builders who lived under strict conditions, close to those of the current day corals, and can easily be recognized because the outer shell is finely lined. Ammonites are perhaps the most widely known fossil, possessing the typically ribbed spiral-form shell; they became extinct along with the dinosaurs and belong to a group of predators known as cephalopods, which includes their living relatives octopus and squid.
In order to log this Earthcache as found, locate the tiny limestone strata near the cache coordinates and, by walking over them, observe the presence of fossils.
1. Can you see any rudists? And/or any algae?
2. Take now a look at the infopanel located nearby: there you will see the image of two nice ammonites, and a photo of the fossil marine reptile. Can you measure the reptile's lenght?

[HR] Područje oko uvale Brbiščica napravljeno je od karbonatnih stijena nastalih stotinu milijuna godina, ispunjen sitnim fosilima nevidljivim golim okom, ali i čistim, koji pokazuje puno fosila velikih organizama. Osim uobičajenih fosiliziranih školjaka toga doba, vidljivi su i rudisti, također amoniti, fosilizirane alge i ribe, te je pronađen iznimno vrijedan fosilni morski reaktor.
Rudisti su bili graditelji grebena koji su živjeli pod strogim uvjetima, bliski onima današnjih koralja, i lako se prepoznaju jer je vanjska ljuska fino obrubljena. Amoniti su možda najpoznatiji fosil, posjedujući tipično rebraste spiralne oblike; oni su izumrli zajedno s dinosaurima i pripadaju skupini grabežljivaca poznatih kao glavonošci, što uključuje njihove žive rođake hobotnice i lignje.
Da biste prijavili ovu Earthcache pronađeni, pronađite sićušne vapnenačke slojeve u blizini koordinata predmemorije i promatrajući ih, promatrajte prisutnost fosila.
1. Možete li vidjeti bilo kakve rudiste? I / ili bilo koje alge?
2. Pogledajte sada infopanel koji se nalazi u blizini: tamo ćete vidjeti sliku dva lijepa amonita i fotografiju fosilnog morskog reptila. Možete li mjeriti njezinu dužinu?
