Brachipods Found In Hungry Hollow Last Few Weeks

[lmacfadden]

Here are some of the brachiopods I have collected in the last few weeks from the river's edge (Ausable River) near Hungry Hollow, Ontario. The water level is low enough to expose some great piles of stone to sift through! Most fo these are weathered but I love the diversity... and I like treasures in my pockets!

Very nice, Lise!

Love it when they are so 3-d like that.

Thanks for posting them.

nice assortment of brachiopods

I'm definitely going to have to visit Arkona during my next trip north. Nice finds!

Most of the brachiopods pictured are Mucrospirifer thedfordensis. The wide ones in the sixth column are Mucrospirifer arkonensis. The small one in the fifth column is Cyrtina sp. and the one below that looks like it may be an Atrypa but not sure. The thedfordensis come from the Widder Fm. which are the top layers and the arkonensis come from the Arkona Fm. which is the bottom layer. The Cyrtina probably came from the Hungry Hollow Mb. which is the middle coral zone.

Nice specimens.

Perfect! Thanks for the help with identification. It was exciting finding the cyrtina (my sister had found 2 smaller ones that same day) since it seemed more rare than the other brachs (and I had never found one before). Woulld love to find a whole mucrospirifer arkonenensis complete with wing tips which I know is highly unlikely without a matrix... but I'll try anyway!

Looks like you are getting quite the collection!!! Love those!

Awesome brachiopods! Thanks for sharing.

Great brachs, a pocket full of treasures is always a good day!

[MakoMeCrazy]

Wow. Those are wicked cool! Congrats

Did you find many of these in one particular location? I ask because I
found a pretty decent haul by the high banks on the north side of the
river back in 2011, all in approximately one spot, and most of those
specimens showed the same type of species variation as in the collection
you photographed (mostly Mucrospirifer thedfordensis, few M.
arkonensis, and a few Cyrtina plus one roundish species I haven't
identified yet).

While we're on this topic, would anyone be able to identify what this is?

My best guess at this point is Cyrtina sp., but I haven't been able to assign it to any species of that genus yet. It is more laterally compressed than Cyrtina hamiltonensis, much larger than C. coultisorum, and while it compares favorably with C. arkonensis it has a very clear "wing tip" on one side that i haven't seen in that species so far.

I found them somewhere along the Ausable river on the low banks between Hungry Hollow and Rock Glen. I doubt that I could find the exact spot again.

The one you have there looks just like a cyrtina... a nice big one! Good find!

Wow. If that many turn up in the gravel, they must really be something closer the the source exposure(s). Have you tried to track any down?

No I haven't. I started finding them and placing them in my pocket and before I knew it, there were a couple dozen of them in my pocket a few hours later. I never thought of tracking them.

[Regg Cato]

When I found a couple dozen in the gravel back in 2011 the river was
just receding, so I didn't make much of an effort to look for a source
exposure, though it almost seemed like they were from a small (<1
meter) outcrop under a tree.

Well that's what I figured, but i want to know what species too lol =D

Nice brachs! I like to call 3D ones "butterfly stones".
