A Fossil A Day.....

[Wrangellian]

I agree about the good photography and very nice fossils, I particularly like the first one, and the Poterioceras is interesting too.

BTW the Pennsylvanian is either a period or a 'sub-period' (I think it should be an epoch, but whatever). In any case not an era.

Per the International Commission on Stratigraphy, the Pennsylvanian is a Subperiod.

Shark Ctenacanthus sp. Dermal  1/4 inch

Nice fossils! I think though that this might be an inarticulate brachiopod rather than a dermal denticle.

@DPS Ammonite and @Wrangellian - thanks for the clarification. I tend to just say Era when posting on Social Media because saying Texas Pennsylvanian Period confuses the heck out of not paleontologists. But I should use the proper terminology when posting on FF! 

 

@connorp - this was ID confirmed by Bob Williams of the Dallas Paleontological Society (he wrote a book on Texas Pennsylvanian fauna).  Here is a pic of one he has:

It's the only one I've found so far! A friend found one as big as her thumb at another location....but they are definitely not a "usual" find.

They are not a usual find here either. I have found a few impressions and pieces, but only 1 decent sized one that was mostly intact.  It’s nearly 4 inches long if memory serves.

 

Since a decent one is uncommon in the formation I find them in, I get excited when anyone finds one. Congrats!

Fossil for Today: 

Goniatite Uddenites sp.

Size 1/2 inch 

 

[Misha]

Beautiful fossil!

Goniatites are really interesting,

Is it filled in with hematite? That would be interesting as I only thought that occurred in those Devonian moroccan ones

I included 'period' because Americans used to refer to it as such and you'll see that in older US charts, and didn't think anyone (at least not Americans) would be confused by the use of 'period' even if it has been officially relegated to 'sub-period'. I'm sure that act was one of compromise between the US 'period' and the rest of the world's Late Carboniferous 'epoch', but I think this has made a mess of it.

That's a good question.  Possibly pyritized?

I love crinoid, there's so much variety of form and colors, really photogenic 

[JamieLynn]

@Denis Arcand Yes~ Crinoids are endlessly fascinating!! And there is one spot where I collect these crazy colorful crinoids. I was going to post it at a later time, but here it is as you might particularly enjoy it! A collection of colorful crinoids!

Very nice! We have a lot of crinoids here (especially in the Mississippian) but non that I can think of with such a unique shape.

[Tidgy's Dad]

That goniatite fragment is gorgeous!

[JamieLynn]

@Denis Arcand - yes, me too!! I was lucky to find them all together in one spot, so even though they had disarticulated, I knew they were from the same critter. They have so much interesting detail!
