I just clicked on Ken's link about chitinozoans - very interesting!  So, they may have been containers to hold eggs of marine organisms that lived in the Paleozoic, but they're still not entirely sure - cool stuff!

Added a new life form to my understanding-- chitinozoan!

I do enjoy my envelope being pushed.

Nice chitinozoan pic,Adam

NB:they are hugely important in paleozoic biostratigraphy,assessment of thermal maturity of geological formations and,in some cases ecologically (possibly )significant(teratologies,process lengths biometry,diversity dynamics)

edit: feel i have to clarify/ amplify a bit: well preserved chitinozoa can exhibit quite lengthy processes

Yesterday on the hill. Very lonely. Fossil hash, with lot's of dirt still coming off in the ultrasonic. 

[Bobby Rico]

@Peat Burns beautiful images . @ricardo @Tidgy's Dad @Bob Saunders thank you all very much for add your great photos to my thread and keeping it going. It really is much appreciated . As a thank you this is probably two of my favourite fossils in my collection the claw I have had for 20 years and the lovely tooth was give me by @caldigger. Dimetrodon, Ryan formation, Permian, Jefferson Co, Oklahoma .

 

Dimetrodon is in my opinion the great creature to walk on this planet . 

[ParkerPaleo]

Eumys elegans from the White River Oligocene in Wyoming.

[Tidgy's Dad]

Xenocrinus baeri columnals. Unusual to have square crinoid stems. 

These are just over a mm across for the biggest ones. 

[Bob Saunders]

From lower Michigan. What type of Brachiopod? much prep or cleaning. 

[Bob Saunders]

above the shell is a Fossil Bryozoan, Fenestella sp. forming a slight curve. 3/16th or 0.5 cm. Mississippian to 480 myo. Social distancing. 2nd image at 9 o'clock is before cleaning. 

[TOM BUCKLEY]

How did you ever spot that?

Thought I might join the fun. Here's a cluster of Eurypterid eggs, algae, spores, tiny alien spaceships. These were found in the Silurian of Ridgemount Quarry in Fort Erie, Canada. Just North of Bufffalo, New York. Note that the entire cluster is only 1mm.

Wow that’s probably one coolest additions to this thread. Very interesting and great close ups.

Where is it from? Hash plates are so fun to photograph. I hope you ,wifey and tidgy are safe and well. We did a pub quiz online and one of the questions was where is the oldest university in the world and the answers is?

Thanks Bobby.

I always examine my prepped specimens pretty thoroughly so I tend to discover tiny things. This particular specimen has stumped even the Eurypterid expert, Sam Ciurca. He's the one that suggested algae. The picture that shows a circular view was shot while hand holding a point and shoot camera up to a microscope eyepiece.

I've got a 1mm horn coral somewhere. When I find it I will post pictures.

It's from St. Leon, Indiana, in a wonderful hash sent to me by Ralph. @Nimravis

I'm still working on exposing more pieces on it, and have found four species of bryozoan, six species of brachiopod, four species of crinoid as well as two trilobite pygidiums, three cephalons, a free cheek piece and some bits of Isotelus, I think.   

For more details, have a look at the last page here :

And yes, the University of al-Qarawiyyin, in Fes Medina, is the oldest in the world. It is also linked to one of the holiest mosques In the Islamic World, which is a place of pilgramage (but not now!) and an ancient library with many amazing ancient scholarly and religious texts. It was founded by Fatima al-Fihri in the year 859.

Hi Tom, if you are asking about my fossil with the Brachiopd a man from church dug his farm pond with his crane now around 12 feet deep in places.. large row of piles of sand, clay and rocks and fossil. Some around 10 feet high so I am mostly using a small child's rakes to pull down the sand to check for goodies. As the weather improves I will be back with my screens to check for items. near my house so just go as things permit. 

[Bob Saunders]

I will add that all cleaning has been done with a spear shaped larger Xacto blade with magnifiers and a small ultra sonic cleaner. It was pretty covered up.

Hi Bob.

I was actually referring to Ricardo's 1mm tooth in a coprolite. After being away for a few years I'm a little rusty with my posting.

two from Sunday. not sure what type of Brachiopods they are? 0 .8 cm average width.    #2  1st image has pyrites on one area. 

[Bob Saunders]

a fragment of encrusting holdfasts. It's kind of like a root that grows around an object, which holds the crinoid in place. Allegan County, Mich. 0. 4 cm or 1/8th inch

Thanks Bobby for starting this wonderful thread. I thoroughly enjoyed looking at all the photos and posts.

I took these pics with a $5.00 clip-onto-the-phone toy microscope, so I hope you won't mind the mushy quality of the images and will enjoy the photos anyway.  I'll start with simple crinoid bits found at Lake Michigan beaches.

 

Side of a worn crinoid stem with lovely beekite growing on it, which are too small to see by eye:

   

 

Here a couple of crinoid columnals with varied center pores:

      

 

And a close-up of a tiny (1cm tall) crinoid calyx (upside down):

Wow no thank you Pippa . Beautiful images and at a bargain price bit of kit. The little  crinoid calyx is beautiful.
