Max-fossils

Rotterdam in the distance here. There were more people on the beach than usual, but then again, it was the first 'warm' Sunday in a good while.

The white tower you can kind of discern in this picture approximately marks the center of the Zandmotor.

I may like fossil shells better, but do also have a weakness for modern ones too. And seeing this huge Mya arenaria shell just laying there (it was dead unfortunately) with the whole body still there is pretty cool. This specimen was surprisingly big.

Onto the actual finds I made!

Just to illustrate the incredible diversity of shells we have here, I will show at least one couple of pictures of each species found today! So also the common and fragmentary ones will be shown, just for the fun of it :D 

All these shells are from the Eem Formation; Eemian interglacial, Pleistocene (unless stated otherwise). 

 

1) A perfect Mimachlamys varia scallop

2) A fantastic egg cockle, Laevicardium oblongum crassum

3) My favorite find of the day: a small and kinda worn Gari fervensis. But this species is rare, and I love it very much, so I was super happy to find this one :) 

I have a much better example that I found on the Maasvlakte 2 a long time ago, you can find it in the TFF Collections. My new one is nowhere as nice as my older one, but it's my first one of the Zandmotor and that's good enough to make me very happy :D

5) I often talk about this weird dude, the Corbicula cf fluminalis! We still don't exactly know how old this freshwater critter is, but it's not Eemian (maybe 400'000 years old?)...

6) Gotta love the artemis shells!!! Here we have a gorgeous Dosinia exoleta

7) And its equally gorgeous little brother, Dosinia lupinus :D

8) A surprisingly well-preserved incomplete shell from something in the Pharidae family (I still need to figure out which one, they're a pain to identify). You don't often see them with the hinge in such a good condition!

9) And another Pharidae family shell piece. This one is clearly a different species, but I also don;t know which one. Got some IDing to do, but luckily I have all the documents necessary.

10) A quite small and beautiful Acanthocardia tuberculata specimen. I found a bunch of them, but most of them are massive complete ones that are nowhere as cute as this one :P

11) And this one is very cool... might be just a fragment, but its sculpture is just good enough to see that this is part of the much rarer Acanthocardia echinata! A first for me, good to have this species be confirmed on the list :)

12) A very big specimen Cerastoderma glaucum, a common species, but rarely in this size (and with such a nice blue hue).

13) The boreal astarte shell, Tridonta borealis. Also a weird one, because it's a coldwater species (still alive around namely Iceland) yet found in warm Eemian localities... Scientists are thinking it might be a bit younger, from the Weichselian, some 80'000 years old.

15) Followed by another one of the same species, but this one is very ugly! Still perfect though. Pathological specimen? I think I like it even more than the normal perfect one :D

16) A very nice Anomia ephippium, easily mistakeable with the common oyster Ostrea edulis if you don't look well enough.

17) Speak of the devil... here we have a common oyster! Ostrea edulis. Although to be honest, this species isn't exactly the devil... that title is better suited to the Japanese oyster Crassostrea gigas, an invasive species that is driving our common oyster to extinction :(  Or are humans the evil ones for having brought that species here? :headscratch:

18) And another smaller one of the same species, with slightly better conservation.

20) Followed by their much more common brother the Venerupis senescens, a species sometimes used as guide fossil for the Eemian.
