February field trip in the late Devonian of Belgium

Recommended Posts

It has been a while that I made a decent field trip.

Past Sunday I left with 2 friends to a quarry in the Ardennes from Belgium.

Last year we made a few visits to that place with great success and a fair number of late Devonian cephalopods were found.

So hoping to add a few goniatites to our collections we left early in the morning. The weather conditions for the trip were terrible: it was raining and the wind was blowing very hard.

Before we got to the quarry the rain stopped, but there was still a lot of wind. The rain had turned most of the flat parts of the quarry into a muddy swamp.

But the heavy wind blew the last dark clouds away and we started our prospection in the slag heaps on top of the quarry.

The first corals where collected, mostly hexagoniaria and a worn goniatite .

I made my find of the day in the first 30 minutes in the quarry: In one of those slag heaps I found a large boulder with a large orthocone on it. The specimen was deformed during fossilization, but after clearing the specimen out it proved to be a complete orthoceras of 25cm in length.

This was a monster compared to the most specimens I found there before.

The next stop was a level lower in the ancient part of the quarry, here they were dumping the rocks that where not suited for production, but luckily for us, lots of fossils could be found in them.

This was the most productive part of the day. Although they were hard to find, each of us found at least a couple of decent goniatites.

The rest of the day we spent in the back of the quarry where lots of corals can be found and sometimes a nicely preserved goniatite. Multiple mineral veins are also present with large barite and calcite crystals.

Sadly with the expansion of the quarry the part with the corals was cleared with bulldozers and fossil finds where rare at that location. Still I managed to find an exquisite goniatite specimen, a little damaged, but with very clear suture markings.

My two friends searched through the mineral veins and found multiple good quality barite and calcite crystals.

Meanwhile I prospected other parts and collected a little bag full of small corals and crinoid stems.

(Back to the car with heavy Calcite and Barite cristals...)

Usually we end our day at a local tavern for a drink, but this time I was too tired and I still had an hour drive to home.

I’m already looking forward to my next field trip on 21/02 Then we will be prospecting early carboniferous deposits.

Nice finds, Kevin! Are you going to show us more once the prepping is done?

Sure ;) now you can only see the rough shape of the fossils. I'll prep some of them this week and then post the pictures.

Thanks for sharing.

It's interesting that you find the colonial corals at the same locale as the cephalopos. I rarely have. Corals, crinoids and brachs together but not cephalopods

Nice job on the goniatite.

In the quarry the lagunary deposits are actually next to the reef. So it is not unusual to find larger corals that broke off from the reef due to a storm and dropped further into the lagoon, you can find on regular occasions such corals upside down in the sediments.

There are hints in those sediments of mass events like major storms or such where you can see the bottom of the lagoon covered by a layer of reef inhabitants.

On this 1st picture you can clearly see the lagunary deposits in nice layers on the left. The white/grey massive rocks on the right is the actual reef.

This is a good piece where you can clearly see all the broken leftovers from reef inhabitants dropped further in the lagoon:

The "mash" is generally the most interesting in my opinion! So much info in them.
