Cretaceous of Limburg

[Fossilsforever]

Hello all,

 

Today I found some very cool (and rare) Cretaceous fossils in Limburg (The Netherlands).

Belemnites, one sea urchin (Echinocorys sp.) and 2 rare Phragmocones (from Belemnites) were also found (two on the left corner). 

And also sharkteeth!

 

Can anyone help me with identifying the shark teeth? (max size is 1 cm). 

 

Kind regards,

Ruben

Nice finds!

Neat.

Can't help you identify them, unfortunately (may be @ziggycardon or @Indagator can, however). But very cool finds! That must have been a very rich spot! Where did you find them, if I may ask?

[Indagator]

nice finds. identifying these shark teeth will be tough. they are quite worn down or not complete enough for determining the species. The ones with the green line are likely crow shark but this is just based on the overall shape. Then there are two teeth that are from what i can see not shark teeth but fish teeth. About number 1, I am not 100% sure though. A close-up with better light would be helpful.  (if possible also a close-up of the tooth to the left of 1) 

 

1.  Cimolichthys sp. ?

2.  split tooth of an Enchodus sp. 

 

 

could you also make a picture of the other site of the sea-urchin? Can you share the name of the layer (if you know this) you found these in? 

 

Regards,

Arno

Today I found two other small sharkteeth and at a different location, one Echinocorys scutata (Leske, 1778). 

@Arno: the sharkteeth are really small, the biggest one is 1 cm (at the photo).

John Jagt answered that the shark teeth are perhaps Miocene/Pliocene sharkteeth, but at the Selzerbeek? (thats not possible while there are Cretaceous sediments).

 

Is it possible to show the sharkteeth to you (make a personal appointment and that you look at them?)

I have to agree with @Indagator these teeth are rolled and worn down which makes identification very hard to say the least.

I also agree with the possibility of the teeth circled in green being Crow Shark due to their shape. 

As for the other teeth I don't really dare to ID them. 

Perhaps this website might be usefull, it lists a lot of the shark teeth which can be found in the Cretaceous Limestone of Limburg.

But lovely finds, especially the echinoïd and belemnites, where these found in the Selzerbeek? 
And is that a piece of Mammoth molar which lies beneath the echinoïd?

 

Yours sincerely, 

Ziggy

I am not aware of any miocenic/pliocenic sediments overthere. Based on the enchodus tooth i would say that these are cretaceous teeth. I can have a look at it in person but in the end i don't think i give most of the teeth a final identification.

Hi Indagator,

 

I would like to visit you personally and take the fossils with me (then you can see them in person).

I think it is not a Enchodus tooth, but a part of shark tooth (enamel is gone for the most part). 

 

I found them not in a particular layer, but with sifting in gravel/chalk mixed. And yes, in the Selzerbeek. 

@Ziggy: it is not a Mammoth fragment but I think a fragment of a Deer tooth/and or Cow. 

The Sea urchin is a Echinocorys sp. 

 

Kind regards,

Ruben

The teeth (crowns) look like the following:

The needle like ones/long ones are just like Carcharias cf. gracilis (Davis, 1890).

 

The others perhaps:

 

Order LAMNIFORMES Berg, 1958
Family OTODONTIDAE Glickman, 1964
Cretalamna lata (Agassiz, 1843)

 

And/or

 

Archaeolamna ex. gr. kopingensis (Davis, 1890)

 

And/or

 

Anomotodon plicatus Arambourg 1952

 

And/or 

 

Palaeohypotodus bronni (Agassiz, 1843)

 

the question is: are they Cretaceous shark teeth? (a really big chance because how the hell is it possible to find Miocene/Pliocene teeth in a Cretaceous fossil rich river (with Cretaceous sediments and flint) which is only 13km long.
