Histological bone structure of Lower Cretaceous dinosaurs from southwest Istria Z. Kozarić, M. Šparica, Z. Bajraktarević *Department of Anatomy, Histology and Embryology, Faculty of
Veterinary Medicine, University of Zagreb, Heinzelova 55, 41 000 Zagreb,
Croatia (accepted April 1, 1996) Abstract Recently discovered dinosaur bones in submerged near-shore deposits of southwest Istria include one vertebra, one femur, and two rib fragments. They all show well-developed vascularization. The large amounts of primary bone tissue in the vertebral and femoral compacta as well as in one rib fragment suggest that they belong to sub-adult animals which were growing rapidly. The structure of a second rib fragment differs in that it consists of secondary bone. The absence of lines of arrested growth is evident in all investigated bones. This suggests a sustained manner of bone deposition.

Footprints of the Igvanodon dinosaur Footprints of the Igvanodon dinosaur (pictured at the top) discovered on Cape Ploče and the Barban peninsula are the earliest, most fascinating, traces of animal life in the Brijuni archipelago, and whose origins reach back almost 150 million years to the Mesozoic Era. Dinosaurs, as well as other creatures from later periods, such as the diluvial bovine, whose petrified bones have been found on Vanga, had no need to negotiate the wide channel to feast on the abundance of plants. In those days, there were no islands, having emerged a mere 10,000 years ago as a result of geological movements which resulted in the subsidence of certain tracts of land and the subsequent separation of today's Brijuni from the Istrian mainland.

(excerpt) Jedan od ponajboljih i najzanimljivijih poslužitelja s paleontološkim vijestima, uključujući i one o dinosaurima jest http://www.extinctions.com/fossilnews/fossilnews.htm (svakako posjetiti). Dok pisani i elektronski mediji širom svijeta vijesti o sporadično pronađenim kostima dinosaura objavljuju često kao najveću novinarsku senzaciju, otkriće istarskih dinosaura prošlo je i kod nas relativno nezamijećeno. Porto Colone, nedaleko Bala, možda je jedno od najvećih otkrivenih staništa dinosaura u Europi, te krije tajnu o životu ovih životinja prije 130 milijuna godina. Kosti dinosaura pronađene su godine 1992. na mjestu koje je Baljanima "izlaz na more". Znanstvenici govore o mogućnosti da je ondje neka velika prirodna katastrofa masovno uništila dinosaure, te je najvjerojatnije riječ o velikom "groblju". Veliki pomor i prirodna katastrofa do današnjeg su dana sačuvali dobro fosilizirane ostatke, a pretpostavlja se čak da neke kosti mogu pripadati do sada nepoznatim vrstama dinosaura (http://www.foi.hr/~emjanko/hrv/dinosaur.htm). Osim nalazišta na Porto Coloneu u Istri su na desecima mjesta otkriveni i drugi tragovi dinosaura, najčešće fosilizirani tragovi. Mnoga paleontološka otkrića osnova su i za turističku ponudu. Nažalost, istarski se dinosauri nedovoljno koriste u turističkoj promidžbi ne samo Istre već i cijele Hrvatske u kojoj bi takve dragocjenosti trebale naći više mjesta. Primjerice, u SAD i Kanadi, jednotjedno kampiranje u kojem turisti paleontolozima pomažu iskapati dinosaure, košta 400 US$, a predbilježbe se primaju mjesecima unaprijed. I svi sretni: turisti dobivaju tjelovježbu pod užarenim suncem, a znanstvenici, zajedno s nekvalificiranom radnom snagom, dobivaju novac za svoje projekte. Obavijesti i formulari mogu se naravno naći on-line: http://tyrrell.magtech.ab.ca/home.html. Kanada je zaista vrlo dobro iskoristila činjenicu da se Dinosaur Provincial Park nalazi na popisu svjetske baštine (http://www.unesco.org/whc/heritage.htm) organizacije UNESCO. UNESCO (United Nations Education, Scientific and Cultural Organization) specijalizirana je organizacija Ujedinjenih naroda osnovana još godine 1945. s ciljem da putem odgoja, znanosti i kulture unapređuje suradnju među narodima na temelju pune ravnopravnosti. Tko zna, možda jednom na taj popis upe i istarsko nalazište dinosaura. Mora se ipak priznati da je HPT već godine 1994. puštajući u opticaj pravu filatelističku poslasticu na temu dinosaura dostojno obilježila ovo značajno otkriće (http://www.math.hr/stamps/1994/dino.html). Time je eto HPT dao svoj izuzetni prilog kolekcionarima širom svijeta koji su svoj filatelistički hobi suzili na marke posvećene isključivo dinosaurima (http://www.stampcenter.com/dino.html). Izvor:

Another dinosaur in Istria[extract]
A new dinosaur was accidentally found in a quarry "Beram" near Pazin in Istria, Croatia, after the rock has been blasted with explosives. While the Lover Cretaceous dinosaur undersea "graveyard" near Bale consists of more or less scattered bones of various species ranging from theropods to brachiosaurid, this specimen seems to be the complete, articulated skeleton (skull included) with only the tip of the tail chipped off. It is estimated to be about 10 meters long (it is still imbedded in one piece in the rock wall) and about 75 million years old. So it is about the same age as the hadrosaur found last year (?) near Trieste (Italy) which is in the same region (just about 60 km away). However, no expert has seen the new Istrian specimen yet. So, to which family does this dinosaur belongs is still unknown. This find also raises the question again of the possible existence of a land bridge between Africa and southern Europe... Source: |

When the dinosaurs were browsing in Istria A description of a museum in Monfalcone It deals with a permanent paleontologic exhibit. Exhibited are dinosaurs bones retrieved in Istria by Dario Boscarolli, a member of the Museum. These findings are presently under study in this museum. They are primarily vetrebrae and bones belonging to the legs of SAUROPOD DINOSAURS. a portion of the exhibits is dedicated to the dinosaurus footprints discovered in the last few years in several sites in the Istrian peninsula. An introductory glass case explains the location of the various levels of the fossil-bearing strata, and the paleographic position of the Adriatic Region during the Cretaceus period. (Translation by F. Aitala) Quando i donosauri pascolavano in Istria Descrizione Si tratta di un'esposizione paleontologica permanente. Vengono esposti gli ossi di dinosauro rinvenuti in Istria nel 1993 presso il paese di Valle dal nostro socio Dario Boscarolli. Tali reperti sono attualmente in studio presso il nostro Museo. Si tratta soprattutto di vertebre e ossa degli arti di dinosauri sauropodi. Una parte delle esposizioni è dedicata anche alle impronte di dinosauro rinvenute negli ultimi anni in numerosi siti della penisola istriana. Una vetrina introduttiva spiega la posizione stratigrafica dei livelli fossiliferi, la posizione paleogeografica della regione adriatica durante il Cretacico. |

Mid Cretaceous orbitolinid (Foraminiferida) record from the islands of Cres and Losinj (Croatia) and its regional stratigraphic correlation pp. 155-171 (doi:10.1006/cres.2000.0203) A. Husinec, I. Veli, L. Fucek, I. Vlahovi, D. Matiec, N. Ostri, T. Korbar Institute of Geology, Sachsova 2, PO Box 268, HR-10000, Zagreb, Croatia Abstract The mid Cretaceous shallow-water limestones on the islands of Cres and Losinj contain abundant and diversified orbitolinid foraminifera. A biostratigraphy, based on the orbitolinid taxa and their chronostratigraphic interpretation, is proposed for the Aptian, Albian and Cenomanian deposits in the area investigated. Four orbitolinid biozones have been recognized: (1) Palorbitolina lenticularis Taxon-Range Zone in the Lower Aptian; (2) Orbitolina (Mesorbitolina) texana Assemblage Zone in the Lower Albian, the body of strata being characterized by a distinctive assemblage of Orbitolina (Mesorbitolina) texana, O. (M.) subconcava, O. (M.) parva and O. (M.) pervia; (3) 'Valdanchella' dercourti Taxon-Range Zone in the basal Upper Albian; and (4) Orbitolina (Conicorbitolina) conica Abundance Zone in the Lower-Middle Cenomanian, a body of strata in which the abundance of the species Orbitolina (Conicorbitolina) conica is significantly greater than is usual in the adjacent parts of the section, regardless of either association or range. The established biozones on the islands of Cres and Losinj are correlated with orbitolinid biozonations and orbitolinid stratigraphic distributions in the adjacent areas, with emphasis on the Karst Dinarides.
