Gastropod Madness on the Banjaard!

Rule Pliocene!  

The Pliocene did indeed have a rather strong influence this time around!

Pliocene fossils are generally a little more uncommon than the Pleistocene fossils, so I was happy to find so many rarer specimens! 

 

(But the Pleistocene is still the best, no doubt )

Wow, I don’t know how I missed this thread before but that is a very diverse assemblage of Gastropods and a nice big old fish jaw you’ve got there. A great trip report.

Looks like you great day at the beach with your family Max.  Looks like a lot of nices finds especially the gastropods. 

[Al Tahan]

Wow you cashed in! Nice haul and great ID job

Thanks a lot!

I shared the thread about 20 hours ago (and only 10 hours before your comment), so I guess I can see how you 'missed' this thread before

Thanks Adam! I too really like the gastropods. Although I generally prefer bivalves, it makes me really happy to sometimes find some slightly rarer stuff

Thank you!

I gotta admit that for some of the gastropods I am not completely sure of the ID, but I think I got most of them correct. I'm much more confident with the bivalves

Hey Max!

 

It looks as though you hit the gastropod jackpot!!!  Congrats on the beautiful and lucky finds!!!

Thanks Monica! I did indeed hit the gastropod jackpot, exactly as you said. This doesn't happen often!  

[Plantguy]

Congrats Max on the latest finds! Looks like you'll be busy cataloging for awhile.

Wow, that's quite a haul! Never heard of this location before, but great finds! Quite an amount of fish verts too

Thanks Chris! I haven’t started an official catalogue of my fossils (yet), but I do have a good amount of sorting work to go through (putting species together, making/updating paper labels, making small compartments of the correct size, etc). Long and annoying work, but still rewarding and definitely useful

Thanks! I agree, that’s a lot of fish verts indeed! My mother is crazy for fish verts, she loves collecting them. Both her and I were very surprised at the amazing amount of verts we were finding! 

Although the beach itself is not very new, it’s popularity as a fossil location is quite new. Might be because there was a recent beach filling which brought a lot of fossils, or simply no one had really shared the location before. I definitely recommend a visit there!

What a day out with the family!

Congratulations, very well done!

And I am really impressed by your taxonomic skills . There are several Nassarius/Tritia/Hinia species in "my" Miocene, but I am always at a loss assigning them to a species, despite having a perfect revision paper by Harzhauser at hand...

Thank you Franz!

According to WoRMS, quite a few of the Nassarius species have been moved to Tritia (N. reticulatus, N. nitidus, N. pygmaeus, N. incrassatus, etc are all Tritia now). 

I'm not fully ready to move the genus name yet though, I'm waiting for the 2nd part of 'De Fossiele Schelpen van de Nederlandse Kust' to come out. I have the 1st part (which has all the documented Dutch fossil bivalve, chiton and scaphopod species), and it's the book that I refer to the most when IDing my finds, and I use the same names as that book. The 2nd part will talk about the Dutch fossil gastropods, and I'll change the names accordingly to that book. The book is made by a handful of my favorite paleontologists (and the best ones when it comes to Dutch fossil shells), so I trust it easily  

While waiting for that book to come out, for now I use a small handbook which shows the most common fossils (all kinds) found on the beaches of Zeeland when IDing gastropods. Although very useful, it doesn't have all the species and doesn't have as much scientific accuracy as the book I'm waiting for. So I often come back on my ID's (in fact, I'm chaging a couple of the species names I put here; look for the edited posts). Gastropod taxonomy is such a difficult thing to do!!!

Thanks, Max, for the explanation, you are doing a really good job!

Very wise! Next paper will probably change genus assignment again !

(A local expert calls this "genera-chess", moving species from one genus to another and back every few years, like playing chess with the species...)

It's very annoying, isn't it? This game of chess seems endless!

[Max-fossils]

Here is a full species list of all the things found!

I'm including the number of specimens found, and their age for each.  

• (E) = Eemian, Pleistocene (120'000 y)
• (PL) = Pleistocene, not Eemian
• (P) = Pliocene (usually late Pliocene, approx 2.5 - 3 my)
• (N) = anywhere in the Plio-Pleistocene, where a more precise age can't be given
• (frag.) = incomplete specimen

 

BIVALVES:

• Acanthocardia tuberculata (1x) (E)
• Cerastoderma edule, forma major (3x) (PL, ~ 80'000 y)
• ?Cerastoderma edule (juvenile?)/?Parvicardium exiguum (2x) (E)
• Mimachlamys varia (1x) (E)
• Macoma balthica (3x) (E)
• ?Mactra stultorum plistoneerlandica (frag.) (E)
• Glycymeris sp (frag.) (N)
• Laevicardium oblongum crassum (frag.) (E)
• Mytilus antiquoruum (4x) (frag.) (P)
• Tridonta borealis (5x) (PL, ~ 80'000 y?)
• Mya truncata (5x) (frag.) (E)
• Zirfaea crispata (1x) (frag.) (E)
• Angulus fabulus (2x) (1x frag.) (E)
• Ostrea edulis (2x) (E)
• indet. (frag.) (age unknown) --> I'm thinking it's one of those weird Eocene species that sometimes get mixed in the party... I'll do some more research
• Corbicula cf fluminalis (1x) (PL) --> freshwater species
• Spisula subtruncata (2x) (1x frag.) (E)
• Spisula solida (2x) (E)
• Spisula elliptica (4x) (E)

GASTROPODS:

• Colus curtus (1x) (frag.) (P)
• Planorbis planorbis (1x) (N) --> freshwater species
• Capulus unguis (1x) (frag.) (P)
• Nucella lapillus (12x) (E)
• Boreotrophon clathratus (2x) (E)
• Boreotrophon truncatus (1x) (E)
• Littorina littorea (3x) (E)
• Littorinidae indet. (1x) (N)
• Euspira catena (4x) (3x frag.) (E)
• Ocenebra erinaceus (6x) (1x frag.) (E)
• Cytharella substriolata (2x) (P)
• Epitonium sp. (1x) (E)
• Nassarius consociatus (4x) (1x frag.) (P)
• Nassarius incrassatus (14x) (E)
• Nassarius nitidus (9x) (1x frag.) (E)
• Nassarius pygmaeus (2x) (E)
• Amauropsis islandica (3x) (E)
• indet. (3x) (N) --> I'm still trying to figure out what these little things are, and I'm afraid that they are freshwater species!  
• Aporrhais scaldensis (1x) (frag.) (P)

TUBE WORMS:

• Spirobranchus triqueter (13x) (N)

FISH:

• indet. vertebrae (15x) (1x frag.) (PL)
• indet. jaw (1x) (frag.) (PL)

OTHER VERTEBRATES:

• indet. bone pieces (2x) (frag.)(N) --> probably mammal

 

Well, that's it! Quite a cool diversity of finds imo  

If you want any individual photos, I have them available, just let me know. 

Also, if you wanna know where I got a certain ID from, as in which source, let me know too.

Or if you have any other questions, I'm all ears  

 

I will signal any edits to the species and/or ages that I make here too.

Oh yes, but the intensity depends somewhat on the fossil group.

I have started a thread about this "problem" about half a year ago.

The winner you can already see in the link above...
