Show a few fossils, that are from the same state. Can we show all 50 States?

Is this another recent reclassification? We bought it a year or two ago, and our "Trilobites of New York" book (Whiteley, Kloc and Brett, copyright 2002) lists both Basidechenella and Pseudodechenella as species found in New York. Our specimen was found in the Hamburg, NY area.

 

 

The original classification and reassignment of Basidechenella to Pseudodechenella in North America is from Pillet 1972. In the book "Trilobites of New York" this is an oversight and a topic of confusion. The book acknowledges Pillet 1972 on page 157 but also contradicts this by listing B. clara / B. canaliculata / B. hesionea  in Table 5.8 (Proetids of New York).

Thanks! We'll update the tags. It's always good to be current with the nomencalture.

I don’t think Oklahoma has been mentioned yet.

Dimetrodon, was such an ancient looking creature.  It calls to mind the far distant past, for me.

No Colorado?

Here are a few,

 

Unidentified Leaf from Florissant Colorado, Eocene age.

 

Unidentified flying insect, Florissant Colorado, Eocene.

 

Gyraulus florissantensis, from Florissant Colorado, Eocene.

 

And finally, petrified wood of the family Lauraceae, from the Dawson Arkose Formation, Arapahoe county, Colorado, late Cretaceous.

Also a quick map, all the states in red have at least one fossil shown for them, and the ones in green are completely unrepresented so far.

I have tried to hold back, and allow others to post fossils from Mississippi; since many of mine, are in poor condition.  The shark teeth coming out of the creeks and rivers in north Mississippi, tend to be in better condition; than these recent surface finds of mine.  But, these are fossils from Mississippi.
