From the album: The Mollusca of the Banjaard
A small common oyster specimen, with a nice brown coloration. Fossil oyster shells can be frustratingly difficult to tell apart from modern specimens. Different oyster species can be very hard to recognize, but O. edulis is by far the most common, so it's usually a reasonably safe bet (the other species are rare Pliocene to Eocene species and are very rarely found).

From the album: The Mollusca of the Banjaard
A very small damaged oyster specimen. Fossil oyster shells can be frustratingly difficult to tell apart from modern specimens. Different oyster species can be very hard to recognize, but O. edulis is by far the most common, so it's usually a reasonably safe bet (the other species are rare Pliocene to Eocene species and are very rarely found). Note: this particular specimen is pretty cool, because it's a great example of bioimmuration. Can you see those weird lines on that shell on the left hand side? That's the imprint of another shell species (bivalve or gastropod) which the oyster grew attached to. Status: still locally alive Fossil occurrence: common© 2019 Max DEREME

From the album: The Mollusca of the Banjaard
A damaged specimen, quite worn too. Admittedly, it is much less beautiful than the modern version of this shell, which is commonly found here, but it's still nice to find a fossil example! It is a bit too worn to make a confident ID to species on this specimen, but seeing that most shells are from the Eemian, chances are good that this is the Eemian (and modern) species E. clathrus. But it still isn't completely sure, which is why I put it as cf. just to be safe.

Hi all, Last weekend, there was an excursion organized by the Paleobiologische Kring (a fossil club here in the Netherlands) on the Zandmotor. As you know I had already been quite a lot of times on the Zandmotor, because it is my usual spot. But seeing that a few of my contacts, namely a fossil friend I had met at a fair, Thijs, as well as the curator of the natural history museum in Rotterdam Bram Langeveld (that I know pretty well), were going to the trip, I decided to join in just for the fun of hunting with others. Turns out that was a really smart decision, because their company brought me a lot of luck! The day started off with a small lecture by Bram about the Zandmotor and the finds that can be made there. For most people it was their first time on the Zandmotor, so the lecture was pretty useful for them. Then after that, we went onto the beach to start finding some fossils ourselves. We went from the south side of the beach (Monster), whereas I usually always come from the north side (Kijkduin) as it is closer to my house. The weather was absolutely ideal for fossil hunting. Not cold, but not very warm either. Very little wind, blue sky, few clouds, perfect. During the trip, nearly everyone was looking for mammal (mammoth and other megafaunal Ice Age species) bones. I was, along with two or three others, the only one also looking for shells. As soon as I got onto the beach, I already found a nice partial Mactra glauca, a pretty rare species. A good start already! It didn't take long before some people found mammoth bone fragments. During the hunt, I talked quite a lot to other hunters, especially to Bram and the other shell hunter. Very interesting discussions, I learned a lot of new little details about shell identification. Meanwhile, I was finding some of the most incredible fossil shells! Species that would normally be a trip-maker I found several of, and some beyond-rare species also flashed under my eyes. It was unbelievable how much I was finding! At the end of the hunt, because we went back to the starting point (south side), after having said bye to the others, I had to walk all the way to the north side, so I spent some more time looking, and that revealed even more finds. I couldn't believe how much I was finding! The sun was setting at the time I just left the beach, and that's also when the clouds started to thicken: While walking along the bike path towards the parking where my dad was waiting to pick me up, I made one last very surprising and definitely fun find: a great mammal vertebra! Just laying there on the side of the bike path in plain view. It was pretty sun-bleached, so it must have sat there for quite some time. I was surprised that no one had noticed it before me, but didn't complain either. I suppose another hunter had found it and accidentally left it there? Regardless, it was a fantastic way to finish up this incredible hunt. Apart from the sunset pic above, I didn't take any location (or in-situ) pics during the hunt. If you want to see some more pictures (and finds) from this location you can search the forum for "Zandmotor"; this should bring up some results of the trip reports I've previously made of some of my hunts (I only make trip reports of my most successful/interesting ZM hunts).

Hi everyone, Last month, as I stayed a weekend at my grandparent's house, we decided to go to the Banjaard beach for some fossil hunting. I had asked Bram Langeveld (Natuurhistorisch Rotterdam) and Ronald Pouwer (Naturalis) which one of the "Zeeuwse stranden" (beaches of Zeeland, a province in the south-west Netherlands) was currently the best to hunt at. Both said that they were hearing some good stuff about the Banjaard beach recently, which has mainly Pleistocene fossils (including Eemian shells). Seeing that I can also find Eemian shells and other Pleistocene stuff at the Zandmotor, my usual hunting spot, I was a little reluctant at first, but still ended up going there. Good thing I did, because it was a rather successful hunt! The weather was really nice, bright blue skies and fresh (but not cold) temperatures.

Hi all, A handful of days ago there was a sand pile right in my neighborhood. Not sure why it was there, probably someone was making constructions to their house, but in any case I was happy. That's because that kind of sand comes straight from the North Sea, which is full of Eemian fossil sediments! So I took a little plastic bag and spent an hour or two looking in that pile of sand for fossils. The very common Eemian bivalves came up abundantly (so species like Mactra plistoneerlandica, Cerastoderma edule, C. glaucum, Macoma balthica, etc), but that is not what I was too excited about. Seeing that the sand pile was rather small, it forced me to focus on just that little pile. Which is great, because therefore I actually started looking much more closely, and hereby also collecting tiny micro-fossils! Lots of gastropods, which is awesome because these are not as common as bivalves in these sediments. I namely found a complete yet puny Anomia ephippium, some very small Cerastoderma's, and also the ones attached. I would love to be able to bring these down to species level. So I am asking for your help! The Hague, Netherlands (from North Sea sediments) Eem Formation Eemian, Pleistocene; 120'000 y Thanks in advance, Max #1: Looks a little bit like Macoma balthica, but still a bit different... Very likely from the Tellinidae

Hi all, So on Tuesday afternoon, I was lucky enough to only have a half day of school. Seeing that the weather was nice, and that I had nothing else to do except go home, I decided to take the bus in the other direction, so to Kijkduin, in order to do some fossil hunting! I bought a sandwich and a chocolate bar at the Shell gas station, and set out on the beach. From the beach of Kijkduin I walked south, so towards the Zandmotor, while of course looking for fossils. View of the beach (mind that the sea is on the right side, on the left side it's just a small lagoon), with the haven of Rotterdam in the background. View of the beach with Kijkduin, and then Scheveningen, in the background. (Sorry for the blurriness...)

Hi all, Found this on the Zandmotor, Netherlands. Most likely from the Eem Formation, Eemian, Pleistocene; 120'000 years old. Though most of it is not there, enough of it is present (such as the umbo, and one full side (which allows us to see what the general shape and size would be)) to be identified. I am thinking that it may be Politiapes ruditapes, but that is a wild guess. What do you guys think it is? Thanks in advance! Max

Hi all, What species of Ostrea do you think this is? My first thought was O. edulis, but I am wondering if it maybe isn't O. ventilabrum after all. In fact, how exactly can you differentiate the two different species? It was found on the Zandmotor, Netherlands. Most of the shells found here are (apart from modern) from the Eem Formation, Eemian, Pleistocene; 120'000 years old. And it would be this old if it is an O. edulis (which is a very common species). But maybe it is the rarer Eocene O. ventilabrum? I know that they do occur here too, but I never know how to tell them apart from O. edulis. Looking forward to hearing your answers! Max
