Hi folks!

I´d like to show you some pieces out of my collection. I will start with some nice, little crinoids from the Middle Devonian.

Hope you enjoy ;)

Nils, Welcome to TFF!

Are those known as microcrinoids? Your photographs are very good. Do you photograph through a microscope?

Hi! Thanks for your welcome!

Those are not really microcrinoids, they are only small :) Maybe some are juvenile specimen. I´ve got a few "real" microcrinoids, I can show some when I´ve got better pictures.

I take my photos through a microscope, an old russian one called MBS-10. I fix the calyxes with some putty on a small needle, so they seem to float ;)

Many of those tiny Crinoids I picked up from microfossil-washings, my favorite way to find small echinoderms (in addition to crawling).

Ps: Nice Ostracod on your profile-photo

Nils,

WOW! What a fantastic variety of fossils you have collected! :wub:

As Auspex has mentioned, these are things I haven't seen before.

Thank you for posting them.

Hi guys!

Thanks for your comments :D

these are things I haven't seen before.

That´s the reason, why I´m posting this stuff. I know what you mean, I feel the same when I´m looking at all those wonderfull fossils in this forum.

Evolution is so incredible!

A little addendum to this Fossil:

Matt Friedmann from Oxford University contacted me. This is not Macropetalichthys, it´s the back half of the skull of a lobe-finned fish (Infraclass Crossoptergii).

A warm "Thank you" to Matt Friedmann for his friendly support and determination! :thumbsu:

Cheers,

Nils

I always find it good when professional paleontologists regularly check the hobby forums and then participate in such a helpful way. I've also had such feedback in the past, so it's good to know that we are taken seriously. Of course, it's a boon for this forum in particular that we already have a good number of professional members :)

Hi Roger!
I´ve made the experience, sometimes the best way is to ask scientists directly. I never made any bad experience.

The worst case is, that you don´t get any answer. But that´s ok for me :D

But i agree with your opinion. It is always nice to see, if "hobby-palaeontologists" get involved into scientific work.
Here in the Eifel it works fine. We got some scientists, who constantly get served with material by fossil collectors. It´s a win-win situation for everyone.

Lovely, isn´t it? :wub:

These Brachiopods are quite common in some quarries near Bergisch Gladbach.

Unfortunately all these quarries are now natural monuments, collecting fossils is forbidden :(

I bought or swapped all my specimens.

Thanks for sharing these unique fossils. Quite outstanding.. Most I've only seen in older publications. A lot of German journals are used a basis for understanding our local Devonian paleontology.

I also like the way you collected these. There's often lots to discover when we make an extra effort and change our tactics.

An aside...I'm Canadian but as a young teen lived a year not far north of you in Iserlohn, Westphalia. That is where I found my first fossils. The rocks poured between the rails of the steel railway tracks were often full of excellent impressions.

Hi Northstar, thank you for your comment :)

Iserlohn, that's cool! Nice fossils from there, i know a nearly complete skull of a rhinoceros from Letmathe and lots of devonian stuff from the Massenkalk ;)

I can show a few more brachiopods from the middle-devonian
They´re the most common fossils in the eifel with a very high diversity, and even one of the nicest ..

Hope you enjoy!
