The Polish Jurassic Upland


Recommended Posts

Last week I had the chance to go for a short fossil hunting trip to the area called the Polish Jura – famous for limestone formations, which take several fantastic shapes and have their very own names. Here are some instances:

The camel

The Hercules club

The Trolls

It’s also the area with numerous stone castles from the 14th and 15th century – the are located along the so-called Trail of the Eagle's Nests

Here are some examples:

But my main interest were of course fossil sites. First we visited the so-called Karniowice travertine – academic description says: “they form several lenticular bodies (up to more than 10 m thick) in the lower part of the Permian conglomerates and volcanic tuffs, discordantly overlying the Carboniferous sandstones. Light-grey travertine is locally highly porous or cavernous. It is formed of sparry calcite containing dispersed chalcedone aggregates and impregnations of iron and copper sulfides.“ According to the description it was supposed to be the locus classicus of Dendropupa zarecznyi – one of the oldest gastropods. Nowadays it looks like this:

We brought home a few pieces of the rock, but no Permian gastropods (or anything else, for that matter), in them. They just have really fantastic shapes :)

The second location en route was Płaza quarry – the Triassic site I have already visited before. The place didn’t change much from last time:

except that there were very little fossils available, mainly brachs and crinoids:

obraz.png.ffe52fe0c1b1dd27180eca905f448d2c.png

 

I found these two fossils – do you think the white stuff are pieces of bones?

The other Triassic quarry in the area was unfortunately turned into a shooting range and is no longer accessible :(

The next day we went to Tarnogórski Canyon – which is a former dolomite mine. It’s quite big:

and a bit overgrown

not to mention a little lake in the middle

We searched the rubble for quite a time, but again – only pieces of crinoids:

After such a disappointment, we went to see the Black Trout Adit, which is one of a few Unesco sites in Poland. It’s the only still operating drainage adit in Poland and one of the longest underground boat flows in Europe.

We went 30 m underground and then had a 600-metre “cruise” in metal boats:

When we emerged back to surface, we decided to stop by the Błędów Desert – yes, we do have a desert in the middle of the country :) The Błędów Desert is actually Central Europe's largest accumulation of loose sand in an area away from any sea, deposited thousands of years ago by a melting glacier.

The next day we started from visiting the former capital city of Poland – Kraków:

the home of the Wawel Dragon:

Then we stopped at the Jurassic Mirów quarry:

We were hoping for an abundance of ammos, however there were not so many as in the nearby Niegowonice and several of them partial and very flattened:

obraz.png.078c3980abc9ddbf1f75151338de6867.png

 

They usually are very small:

obraz.png.aa2042c2d890d601c053cad88532a901.png

 

Nevertheless, we managed to find a few things:

Plus a mystery fossil?

The last stop was Młynka quarry – also Jurassic:

obraz.png.c772090d58e663c9773d48d030a7c490.png

 

The most interesting place however was a little ravine next to the entrance – with Callovian rocks:

which turned out to be full of goodies:

And the cherry on top – the crab :)

Thanks, I wish we had a bit more sun - but since it's November, we considered ourselves lucky it was not raining/ snowing :)

To me, as an American the castles are amazing. That in itself would have made a great trip to me just to view them. The fossils would have been a bonus!

Very nice travelogue!  Thanks for bringing us along.

 

Your mystery fossil is a section through an ammonite, showing the surface of a septum.
