Thanks, but I don´t have that stuff any longer. I have turned to other areas with really ugly fossils. Believe it or not .

Franz Bernhard

I enjoy all the fossils you sent, its not only that one even the rudists!

[FranzBernhard]

Ah, time for more ugly upper Cretaceous Kainach Gosau fossils, and a lot it is, from the "Mixed Zone" of the lower Afling Formation:

They don´t look like much, but nothing was known in this particular area north of Reinprechtskogel until October last year. "Fossils are, where you find them."

hip joint vertebra

Maybe just a typo, but this is an atlas, the first vertebra behind the skull.

OH wow, that was the seller's description.
I'll correct it. Thanks.

Today, we are familiar with amphibians such as frogs, toads, and salamanders, but during the Carboniferous and Early Permian, these forms had not appeared yet.  Amphibians were much more diverse.  Many looked like salamanders but they were not salamanders.  Having a long body and short legs was a body type shared by many amphibians at the time and it's not always clear what was an amphibian and what was a reptile especially when the fossil remains are scanty or incomplete so researchers use the term "tetropod" to cover that spectrum.  Some animals of the Early Permian were relatives of early reptiles but were amphibians or at least more closely related to amphibians than reptiles.  Diadectes is a tetrapod genus that was once classified as a reptile but now it is considered an amphibian close to the ancestry of reptiles. 

.

Diadectes was one of the first large herbivorous vertebrates living at a time when complex ecosystems were starting to be established on land and a time when climates were trending cooler and drier.  It was becoming tough to be an amphibian.

 

Diadectes sp.  (rooted tooth)

Early Permian

Ryan Formation

Waurika, Jefferson County, Oklahoma

15/16 of an inch (24mm) long

 

[siteseer]

undetermined metoposaur  (skull fragment)

Late Triassic

Chinle Formation

St. Johns, Apache County, Arizona

roughly 2 x 2 1/4 inches

 

Metoposaurs were temnospondyl amphibians of the Family Metoposauridae.  They had rather flat skulls with intricate ornamentation (pits, ridges, and grooves) on the dorsal surfaces so the skull pieces are quickly recognized in the field.  These animals are found in lake and river deposits and likely fed on fishes and other animals they could swallow whole.
