Dear fellow forum members, I am going through old boxes, in this case with some of my rare own finds (as opposed to bought, gifted and inherited fossils) These I found at a coast of the mediterranean, where the waves gnawed at soft sandstone. On a ledge below the fossiliferous layer there where fragments and some intact shells with and without remaining matrix, and this tooth, without, but weathered and feeling heavy. The shells I could identify (Diodora, Arca) do have living species, Diodora goes back to the Miocene, not sure about the others. So the age could be miocene to "subrecent", or maybe the tooth is much younger than the shells, impossible to tell. Who can tell me whose tooth this was? Thanks J

Simetite (Costa dell’Ambra, Lower to Middle Miocene (~20-12 Ma)

From the album: Fossil Amber and Copal: Worldwide Localities
“Simetite” Costa dell’Ambra Pachino, Syracuse Province, Sicily, Italy Lower to Middle Miocene (~20-12 Ma) Chemical Composition: C: 79.25%, H: 10.41%, O: 10.34%, S: 0.52-2.46% Specific Gravity: 1.056-1.068 Specimen A (Left): 0.6g / 20x10x8mm Specimen B (Center): 0.2g / 10x7x4mm Specimen C (Right): 0.4g / 13x8x8mm Lighting: 140lm LED Entry six of ten, detailing various rare ambers from European, Asian, and North American localities. This is an amber with a rich history. Amber from the island of Sicily is thought to have been known of since the end of the Iron Age (43 A.D.), but did not initially see much use in terms of trade or lapidary: Baltic amber was imported and preferred over Simetite, due to its larger size in general, and also possibly because it was more readily available; Simetite was later traded with the Phoenicians. Lapidary work with this amber dates back to the early 1800s, and was worked using lathes or was carved by hand: rings, necklaces, cameos, and even boxes were crafted using Simetite. Simetite was named after the River Simeto, which originates from the center of the eastern half of the island, flows south past Mt. Etna, and empties into the Mediterranean Sea along Sicily's east coast: historically, this amber was frequently found along Sicily’s eastern coastline below the mouth of the river, and today can still be found in small quantities throughout Sicily’s eastern and southern shores. Although no extensive research has been performed, the in-situ deposits are believed to be located within the center of the island; amber has been noted to become dislodged from clay-filled soil particularly along streams, where it is carried to the ocean. The rivers primarily responsible for the displacement and relocation of amber are: the Simeto and Dittaino, which converge before reaching the sea near Catania, and the Fiume Salso which travels south from the island’s center to the southern shores near Licata. Precious little research has been done in regards to determining its botanical origin, however recent work by Inez Dorothe van der Werf (2016) has suggested the Fabaceae as the source of Simetite. Low levels of cativic, labdanic, and succinic acids are present within Simetite; it also contains varying levels of sulfur (in turn, altering levels of C, H, and O), believed to be due to sulfate-rich groundwater in the deposits: amber is a permeable substance and has been proven to absorb, retain, and release gases (Hopfenberg et.al., 1988, cited by Poinar 1992): theoretically, this property also extends to resins during their burial. There is a completely black form, that is incredibly rich in sulfur, up to 2.46%: compared to Baltic amber, this variety has nearly six times the concentration of sulfur, and roughly half as much oxygen; the color of this amber is determined mainly by its sulfur content.

Hello guys, wonding if you can help me identify this tooth fossil, please? It's been in the family for 70 years or so as it was given to my late father during his time spent in the Navy whilst in the Mediteranean. So we are not sure if it came from either the Eastern side or Western side. Your help will be very much appreciated From the jaw-line to the tip = 10cm Width of tooth at base = 11cm Thickness of tooth at mid-height = 3cm Weight = 870 gms

Hi everyone, There are a few times, I found this funny thing on the beach of carnon, mediterranean coast. I do not think it is plastic, it's rather thick pearl effect ... If anyone knows what it could be, it's will be super! Thank you in advance!

Hello everyone, Archaeological training, when I walk on the beach of Carnon (34) yesterday afternoon, this half vertebra silted next the seashore jumped out at me: However, ichthyology is not my field, I can not determine the animal. If someone know, it would be great! Also, do you think it is old (his red-brown color gives me hope for a fossil)? Thank you in advance! PS: Sorry for my approximative english
