Hey everyone, So today, after my second day of exams, which is why I finished earlier, I had to take the tram home instead of the schoolbus (that I usually take). On my way to the tram station, I noticed that there was some sand on the sidewalk. I looked closer, and saw that there were quite some shells all along the sidewalk. My passion for conchology (which I also have, though it's less strong than my love of fossils) took over and I began hunting for seashells. I only found bivalves, but was still quite surprised with what I got. When I got home, I looked more closely at the shells, and realized some of them were fossils!!! Here is my (unexpected, I should say) haul: 1) Mactra plistoneerlandica (fossil and modern) 2) Cerastoderma edule (fossil) 3) Limecola balthica (fossil and modern) --> I'm really happy that I found some more fossil ones of those, because nearly all of mine were already gone in trades! 4) Donax vittatus (modern) The fossils, found in the streets of The Hague (NL), are probably from the Pleistocene period (they are identical to those that I find on the Zandmotor, which is very closeby). It's really surprising how much you can find, even when you're not looking for fossils. Sometimes you find them in the most unexpected places, and you always get a very weird feeling of surprise and happiness when you do. It's often fun to try and figure out how those fossils got there, and I know the answer to this one: --> Sand is one of the most used resources in the world, and therefore often sought after for (even if it's extremely common). It's useful to build a support for things, such as sidewalks, or to make glass, and many other things. And where is the most sand found? On the bottom of the sea. And in that sand (especially the sand of the North Sea) lie many fossils. So when that sand is pumped upon land, the fossils are brought with it. This is how the fossils came here onto the sidewalk of a street of The Hague. In fact, it's that same sand that composes the Zandmotor, which was built as a natural dam against the floods (which have a bad history with the NL) from the sand of the sea, which is why it is so rich in fossils. I hope that this little report has pleased you, and that you've learned things! Therefore remember to always keep your eyes open for fossils, even if you're in normally non-fossil places! Best regards, Max

Hello everyone! I recently won a "rolling auction" lot that was put up by @digit. Ken sent me a very heavy box that contained the fossils that I won, as well as some additional specimens. This afternoon, while my son was napping, I tried to identify the molluscs that were collected by Ken at Cookiecutter Creek in Florida. What follows are pictures of the specimens that Ken sent me, as well as my guesses regarding their identity (fyi - I searched the online image gallery of the Florida Museum/University of Florida website in order to come up with my guesses). I appreciate any input/guidance that fellow TFF members can give me - thanks in advance!!! Monica Specimens #1 and #2: Bivalves I think that the specimen on top in each picture is Phacoides pectinatus and the specimen on the bottom is Chione chipolana. Please compare with the following images from the Florida Museum: Phacoides pectinatus: http://www.flmnh.ufl.edu/invertpaleo/display.asp?catalog_number=25110&gallery_type=Florida Mollusca-Bivalvia Chione chipolana: http://www.flmnh.ufl.edu/invertpaleo/display.asp?catalog_number=73007&gallery_type=Florida Mollusca-Bivalvia

Hello again! Surprsingly, there's a part 2 to our fossil hunting! This is just as much a surprises for us than for you. Yesterday we went to visit some beaches recommended by the reception. The first one we went to was Benagil. This beach is famous for its huge cliffs, and especially for a special cave only accessible by boat. Unfortunately there was no boat to take us, so we just rested on the beach. That's when I noticed that the cliffs were exactly like those that we saw at Oura (see previous post on the Formação dos Olhos de Ãgua), so I started to look for fossils. And of course, there were plenty! Unfortunately I still didn't have a hammer, as I didn't know we would go fossil hunting again, but I found another way to carve out the fossils from the cliffs. I took a piece of a big (modern) Pectens (scallop), which was shaped like a knife, and scratched around the fossils I saw to carve them out. I was surprised by the softness of the matrix around them: it easily went away with the "knife". As you can see in this picture, there were some recent landslides that occurred. No wonder there's a "Warning: Rock Falling!" sign!

Hello dear fossil-hunters! So here is the report that a few of you have been waiting for: my trip to the Formação dos Olhos de Ãgua! So after a nice breakfast in the sun, we took the car from Vale do Lobo to Albufeira, another coastal city in the Algarve of Portugal. After just a bit of searching, we found a good parking spot for our car. We walked down towards the beach, Praia de Oura, and were amazed by the magnificent view.

On the 26.12.2016 i was in the quarry Moldenberg near Heidenheim an der Brenz. There you can find fossils from the white jurassic. Besides of this highlight: http://www.thefossilforum.com/index.php?/topic/70839-what-is-this/ I also found many brachiopods, bivalves, crinoid stems, bryozoans ... First some pictures of the quarry: Its was a very cold and dark day so shadefully they are not that nice... Now the "real" quarry: And the view on a part of the city Heidenheim:

Since my wife is several months into a 6 month deployment to Hawaii with the Army, I opted to catch a bird out that direction to enjoy a long Veterans Day weekend with her. (Side note: It was recently announced that she'll be promoted from Lt. Colonel to Colonel, awaiting congressional vote at this point. Very proud of her!) Anyway, when we weren't hiking, snorkeling, or surfing, some fossil hunting came into play. Most of us don't associate fossils with Hawaii, being young volcanic islands and all, but there is in fact a thin reef limestone intermittently encircling Oahu. If my sources are correct, this gritty tan deposit is Waimanalo Fm, Pleistocene, about 125 KYA. Concentrating on beaches that omitted collecting of rocks and shells from the posted list of "don'ts", I found a few spots rich in gastropods. I'm way outside my element with Pleistocene shells, so in order to avoid commingling my finds with recent shells, I only took specimens that had to be tapped out of bedded strata or loose boulders. I would have preferred crabs and marine vert material, but for the short time I had available, I was happy to come out with anything from an area "not supposed to hold fossils". Now, a few finds.

The Sunday of the weekend before Hurricane Mathew came a calling, a friend and I decided to spend the day fishing on the Neuse River in eastern North Carolina. WE had a pretty good day fishing, caught lots of small puppy drum and stripers. No keepers but fun to catch. About halfway through the day we left the creek we were in and headed back into the main river. Heading from the Cherry Point area heading over towards New Bern. A mile or so up we saw fish busting all over the surface on the Flanners Beach side of the river but not quite that far. We motored towards them and for an hour or so caught stripers on almost every cast. As we were leaving we noticed there was a small cliff eroding out and decided to check it out. We beached and found small gravel on the beach in a strip about 40 or so yards in front of the eroding cliff face. Now, I have been on this river my whole life, but have never noticed this area before. We started finding bivalves almost immediately. We also found some small worn shark teeth, a nice burfish mouth plate and some possible small bone material. I am trying to pinpoint down the age of this exposure. There is Pleistocene Flanner Beach Formation and James City Formation nearby. James City is earlier. There are also Pliocene deposits. Possibly Yorktown, Chowan River or Duplin. The reason I am adding all of these is because of the bivalve ID's if I have them right. So any help is much appreciated. Please correct any incorrect ID I have as I am still learning how to properly ID Molluscs. The first is a bivalve that according to my reference is known from the Pliocene Duplin Formation; Glycymeris subovata Next an oyster Myrakeena sculpturata, from the Chowan River Formation (Pliocene) by my reference.

Fairly unremarkable specimens, but I encountered these at a potentially new site of river-accumulated deposits. The plan is to make a return and do a proper site investigation. These specimens did not seem to match up with either Stauffer (1909) or Bassett (1935) faunal inventories for the formation. The typical bivalves in this formation include Aviculopecten, Conocardium, Paracyclus and Pterinea. None of these seem to match by visual ID to the specimens pictured here. The specimens themselves came out whole from light beige-grey dolomitic wackestone with conchoidal fracturing, containing spirifers and some trace fossils with little else visible. I'll have to confirm this by exploring the matrix further on some nearby examples. A less than thrilling fossil to ID, I'd still appreciate assistance just for completion's sake
