CRNOGORSKI
Dobrodošli na Željezničku stanicu Podgorica!
Ova stanica je izgrađena nakon Drugog svjetskog rata, a zatim je postepeno nadograđivana do svog sadašnjeg izgleda i kapaciteta sve do 1970-ih.
Šta je amonit?
Amoniti su izumrli morski mekušci sa spiralno uvijenim, komorastim školjkama. Pojavili su se prije oko 400 miliona godina, a nestali tokom kredno-paleogenskog događaja izumiranja (prije oko 66 miliona godina), bez poznatih potomaka.
Školjke amonita sadržale su sve veće, zatvorene komore poznate kao fragmokone, odvojene zidovima zvanim septi. Ove komore bile su ispunjene gasom i tečnošću, koje je kontrolisala cjevčica zvana sifunkula, kako bi regulisala plovnost i kretanje.
Posljednja i najveća komora, tj. tjelesna komora, sadržala je meka tkiva amonita i bila je jedina otvorena komora.
Elementi strukture školjke
A) Tjelesna komora – Najveća i spoljašnja komora u kojoj se nalazilo meko tijelo amonita, pipci, glava i organi.
B) Septi – Tanki unutrašnji zidovi koji su dijelili fragmokonu na brojne komore.
C) Sifunkula – Mala, cjevasta struktura koja je prolazila kroz septe i povezivala komore.
D) Apertura – Otvor školjke.
Zadaci za logovanje
Tvoja misija je da pronađeš amonita koji je skriven ispod žutog heksagona na slici ispod.
Nakon što pronađeš amonita, odgovori na sljedeća pitanja i pošalji mi ih putem e-maila ili preko Geocaching Message Centra.
Pitanja:
1. Prije koliko godina su amoniti izumrli?
2. Koliko je veliki amonit u ovom primjerku?
3. Koji elementi strukture su vidljivi na ovom primjerku amonita prema datom dijagramu?
4. Fotografiraj se (nije potrebno da se vidi lice) ili fotografiši neki svoj predmet ispred lokomotive koja se nalazi tačno ispred amonita, i postavi fotografiju u svoj log pronalaska. Molimo te da na fotografijama ne otkrivaš nikakve spoilere o amonitu.
Logovi koji ne sadrže traženu fotografiju biće obrisani bez upozorenja.

Welcome to Podgoritza Railway Station!
This station was built after World War II and then upgraded gradually to its current shape and capacity until the 1970's.
What is an Ammonite?
Ammonites are extinct marine mollusks with chambered, coiled shells, which appeared around 400 million years ago and disappeared during the Cretaceous-Paleogene extinction event (about 66 million years ago) without known descendants.
Ammonite shells contained progressively larger, sealed chambers known as the phragmocone, separated by walls called septa. These chambers were filled with gas and liquid, controlled by a tube called the siphuncle, to regulate buoyancy and movement.
The last, largest chamber, the body chamber, housed the ammonite's soft tissues and was the only open chamber.
Shell structure elements
A) Body Chamber - This was the largest, outermost chamber where the ammonite's soft body, tentacles, head, and organs were located.
B) Septa - These are the thin, internal walls that divided the phragmocone into numerous chambers.
C) Siphuncle - A small, tubelike structure that ran through the septa, connecting the chambers.
D) Aperture - the entrance to the shell.
Logging Tasks
Now your mission is to look for the Ammonite that is hidden under the yellow hexagon in the picture bellow.
After you find the Ammonite, please answer the following questions and send to me by e-mail or Geocaching Message Center.
Questions:
1) How many years ago did the Ammonites become extinct?
2) How big is the Ammonite in this sample?
3) From the diagram provided which structure elements are visible in this Ammonite sample?
4) Take a photo of yourself (no need to show your face) or with an iten of yours, with the locomotive that is right in front of the Ammonite, and upload it onto your find log. Please do not show any spoilers of the Ammonite in your photos.
Logs that do not attach the required photo will be deleted without warning.
