For the smaller ones i've heard names like eurhinodelphis, schizodelphis.. just assumptions tho.. Link to comment Share on other sites More sharing options...

Balance Posted February 3 Share Posted February 3 Likewise. 😊😁 Currently trying to figure out how to put a jet ski motor in my little boat. Gotta get to more remote places to keep up! Things are not working out well on the cost effective side. 😂😂 2 Link to comment Share on other sites More sharing options...

I'm sure there's some pretty interesting fossil hunting possibilities to this 😉 oh wait, probably not helping with the cost effectieve side.. 1 Link to comment Share on other sites More sharing options...
Balance Posted February 3 Share Posted February 3 (edited) I’ve given up. You can totally get a jet ski motor into a gheenoe but I used up all my weight allowance. So I can go fast in inches of water but I can’t carry anything but me. I’d also basically have to sit on the engine. 😂😂 Edited February 3 by Balance Radness 1 Link to comment Share on other sites More sharing options...

dries85 Posted February 4 Author Share Posted February 4 @Shellseeker I just read this on the Dutch paleontology forum, maybe it can be of any help.. "Several other genera have been found in Antwerp: Aporotus, Archaeoziphius, Beneziphius and possibly Mesoplodon and Ziphirostrum. The most common species are Choneziphius planirostris and Ziphirostrum marginatum" Link to comment Share on other sites More sharing options...
Shellseeker Posted February 4 Share Posted February 4 Dries, You are truly a fortunate hunter to have discovered so many treasures within your reach. Thanks for this Photo of Dolphin teeth.

So, I will start by looking at the Periotics. I only can provide similar looking marine mammal ear bones that have been found in Florida. Whether or not these have the same Genus and/or species names as their cousins in Antwerp is way beyond me.. Top left might be called Pygmy Sperm Whale or Kogiopsis florandus in Florida. Top right might be River Dolphin , Pomatodelphis I will toss in a Bulla for Pomatodelphis inequalis here. The bottom row would be called Delphinus or Stenella ocean dolphins, which are very similar. Compare to your lower right. A couple of more, maybe Stenella ocean dolphins Finally , a nice chart that names (unfortunately only in English ) the various Periotic features.. 3 1 The White Queen ".... in her youth she could believe "six impossible things before breakfast" Link to comment Share on other sites More sharing options...

That's actually the most complete reference work on ear bones i've seen so far 👏 Thx for the work u put into that! In this region for example during the Miocene the sea used to be a lot colder then it was in Florida i suppose, u guys find croc teeth and here it's more likely to find seal for example. So i guess the species of dolphins over here we're probably more adapted to the colder climate, even tho they might have been very alike when i look at your -by the way very neat- collection of ear bones.

dries85 Posted February 4 Author Share Posted February 4 And about these things, over here they're often referred to as stingray stingers of Raja clavata.. Don't know much more about them and haven't found any with the actual spine still intact. This is what a recent one looks like.. 3 Link to comment Share on other sites More sharing options...
Shellseeker Posted February 4 Share Posted February 4 Interesting comment on the temperature of the seas in the Miocene. Here is one of Bobby's pictures on the Beluga Whale from his blog.: And a discussion by another scientist. I found my 1st one in South Florida Peace River Formation in April 2022. And then a 2nd 10 days ago !!!! Every time I find something spectacular like this. I do a little jig, sort of dancing in the river. Note that I found two, one is a left and the other a right.

Boesse Posted February 4 Share Posted February 4 20 hours ago, Shellseeker said: This is not a beluga, nor is it even from a delphinoid - it's got an anterior bullar facet, which is present only in non-delphinoids. I bet this one is a Miocene eurhinodelphinid of some sort. Enjoy. 1 Link to comment Share on other sites More sharing options...

Balance Posted February 5 Share Posted February 5 (edited) Whoa! Found a eurhinodelphinid whale skeleton online. It looks like a cross between a marlin and dolphin and a seal. Bonkers….

Boesse Posted February 5 Share Posted February 5 Alright, here's my attempt at IDing these Belgian discoveries: 1-3 are all delphinoid bullae (Delphinoidea = Kentriodontidae + Delphinidae + Phocoenidae + Monodontidae) 4 is a peculiar periotic I don't immediately recognize but it resembles kentriodontids in some ways and sperm whales in others. It seems to have a pretty large fossa on the anterior process for the accessory ossicle, which further could suggest either. It's not a beluga periotic. I don't recognize this form from contemporaneous assemblages on our side of the pond (e.g. Pungo River Limestone, North Carolina - which has a nearly identical cetacean fauna to the mid Miocene of Belgium/Netherlands). 5 is much more straightforward - that's a eurhinodelphinid periotic, probably Eurhinodelphis or Xiphiacetus. 6 Link to comment Share on other sites More sharing options...
dries85 Posted February 5 Author Share Posted February 5 Thanks @Boesse and @Shellseeker for your reflections on these ear bones. As i know they're not often found in combination with teeth or bones, which makes it hard to ID them. But i got already more than expected 😀 much appreciated! And it keeps the thread alive while i don't have time to go out hunting.. 1 Link to comment Share on other sites More sharing options...
dries85 Posted February 9 Author Share Posted February 9 I went to Antwerp city center to pick up a birthday gift for my girlfriend today. Had 2 hours of free time left so i decided to look up a piece of fallow land in the city where i have found some high quality shark teeth in the past. Too bad the site had been turned into a construction site with a layer of 1,5m dry concrete on top of the Neogene Sands. They were kind enough to put a little pile of fossil sands on the side 😀 These particular sands contain a lot of clay and are normally very difficult to sift, but thanks to the extremely rainy weather the past two days there where some big pools. Which i used to wet sift the fossilicious pile.. A lot of big pieces of marine mammal bone fragments and glycymeris shells with the occasional shark tooth in between. Sperm whale tooth i think.. Some eye finds.. and some other interesting pieces i need to clean up first.. Had a great quick hunt actually, thx for watching, Dries 5 Link to comment Share on other sites More sharing options...
