Natural Science Forum / Biology / Paleontology / December 2004found in spain, better links
Excuse me, some of the links did not work. I just try again, with not-danish letters and no spaces..... I do not know, if this is the right place, but i want to know something about the so called "Níjar-Sorbas bassin" in the south-East of Spain. I have a house there, and my 15 years old son is very interested in the nearby river-bed, where a lot of fossils is to be found. Do anybody know about it, can anybody tell us about our finds, or can anybody tell us where to get answers? pictures here: http://www.baekhoj.dk/spain/soepindsvin.jpg http://www.baekhoj.dk/spain/ben.jpg http://www.baekhoj.dk/spain/fast_skal.jpg http://www.baekhoj.dk/spain/skal_fra_oven.jpg http://www.baekhoj.dk/spain/skal_indv.jpg regards, poul, denmark Hi Paoul Nice clear photos. > http://www.baekhoj.dk/spain/soepindsvin.jpg Echinoid (sea urchin) > http://www.baekhoj.dk/spain/ben.jpg ?? Fragment > http://www.baekhoj.dk/spain/fast_skal.jpg Pecten (Scallop shell; like the oil company logo) > http://www.baekhoj.dk/spain/skal_fra_oven.jpg Hard to tell from this view, most probably an oyster but just possibly a brachiopod (lamp shell) > http://www.baekhoj.dk/spain/skal_indv.jpg The other side of the one above? Oyster. Obviously a shallow-water marine deposit, Age? Living in the antpodies, I am not familiar with the rocks or fossils from this region but it looks very recent to me, Pliocene or later? -- Henry Bartlett I am very much a newcommer in this area, i have tried to find something online about it, but what i find is too hard for me to read. (By the way, excuse my bad english...) Like this, about the actual place: http://www.geo.uu.nl/~forth/publications/Fortuin_2003.pdf What i understand (i believe) is, that it is a messinian reef, that has been elevated very quick and remained dry ever after. Therefore, the structures are in a very good condition. Some of the shells looks like just found by the see. The altitude of Níjar now is about 300 meters. The riverbed, where we find the fossils, is running from the village of Níjar along the Sierra Alhamilla and along the reef. (You can see a map in the link above) What we specially wonder about, is the "Fragment". It looks like part of a rib, maybe from some sort of a whale. Where it is broken, and in the end, it is possible to see the inside structure. It has this creamy color about 1/2 cm from the outside. In the center it has a darker brown color. > Hi Paoul > [quoted text clipped - 25 lines] > -- > Henry Bartlett (By the way, excuse my bad english...) Very much better than my Dutch 8-) > What i understand (i believe) is, that it is a messinian reef The last stage of the Miocene; I was close in thinking it may have been Pliocene 8-) > What we specially wonder about, is the "Fragment". > It looks like part of a rib, maybe from some sort of a whale. At around 14 cm long and 3cm across? It would have been a tiny whale 8-) It looks much more like a piece of shell to me, Regards Henry -- Henry Bartlett hi, Henry. > Very much better than my Dutch 8-) and better than my Dutch too, i hope. I am Danish.... :-)) > The last stage of the Miocene; I was close in thinking it may have > been Pliocene 8-) Yes, congratulation. Some guy from a Danish university wrote to me, that it might be eocene (:-)) . But i do not know. As i told you, i am a newcommer to this area, maybe there are much older layers there also, i only have read, that what makes the area very interesting for geologists is the messinian layers. In this period the whole mediteranian for some reason was emptied for water. Must have looked fascinating! In this area there was some basins, in some way connected to the Atlantic Ocean. > At around 14 cm long and 3cm across? It would have been a tiny whale > 8-) There ARE tiny whales around. Dolphins and porpoises are modern examples... It just looks very much like a piece of a rib, and i do not think it is human ;-) > It looks much more like a piece of shell to me, The guy mensioned above suggests it is from a turtle. regards poul |
