One of my smaller slabs from a construction site in the Tarrant formation had a few interesting little fossils embedded that I can’t identify without trying to extract them. Any ideas? Or not a fossil? The Tarrant formation, south Tarrant County TX.

Exploring a nice sample of Post Oak Creek micro matrix was a new fossil adventure for me. Each new matrix comes with an additional learning curve, and I have managed to identify most of the finds in this one with the help of the excellent collections of fellow TFF members: @ThePhysicist, @JamieLynn, @EPIKLULSXDDDDD, @Jared C, and the informed opinions of @Al Dente and @MarcoSr to name a few. I am also an avid collector of PDFs regarding each new matrix that I explore. I could use some help with these 4 finds. The scale is 1mm in every image. I am having trouble deciding if they are Onchopristis dunklei or Ischyrhiza mira, or something else altogether… Thanks for looking

From the album: Squamates
When I initially found this I was hoping it was Mosasaurid, however upon some reading, I decided it's more likely to be a sister group squamate. In particular, the labial sulcus convinced me it is probably C. crassidens (see Caldwell 1999). It is however much larger than any Coniasaurus teeth I've seen published. -

I'm pretty sure these are S. raphiodon teeth. They are much smaller than S. texanus with a narrow main cusp and finer striations than S. texanus. Compare: http://oceansofkansas.com/sharks/Kansas/shscap3.jpg -
From the album: Post Oak Creek
I'm fairly certain this is a posterior Cretodus - a shark known for producing Texas-sized teeth! At just 1 mm tall, this may be the smallest Cretodus tooth possible. -
From the album: Post Oak Creek
The famous "ginsu shark" is a rarer species that can be found here. This is a lateral position; a tooth farther back in the mouth. I've only found a handful and none are complete. -
From the album: Post Oak Creek
Symphyseal teeth are found in the midline of the shark's jaw. They are usually small and squashed-looking. Since only a few rows produce these teeth, they are much rarer than other positions. -

The fossils in the creek can have varying levels of preservation: from the pristine glassy enamel seen at the top, to more river-worn seen below. -

These oysters are common in the creek, and support the Turonian age of the fossils. -

I went back to the same spot today as last week and cleaned up.

I'm a rookie. This is my second post. I've been out on two "expeditions" and made some interesting finds. When I picked up this fossil?, I noticed it was caulked on the back side, I found that perplexing. North East Texas, Fannin County, Eagle Ford Group, Ozan Formation, North Sulfur River Bed. It appears to be a vertebra. Please help identify. Thanks!

On Sunday afternoon I went out with Keith Minor to a North Texas site exposing the lower Arcadia Park formation and (possibly?) the top of the Britton Formation (lower Turonian, upper Cenomanian respectively). The hunt almost never happened after various storm cells were menacing us and the high winds were thrusting cranes into sky scrapers and whipping up emphysema inducing dust clouds. Yet, even though everyone around us was getting Kansas blown at them, we were only exposed to the high winds and rain so cold and blown so hard that it felt almost like hail. But that lasted for only a few minutes, leaving the rest of the day to muck around in the Turonian while the winds blew most of the clouds away by hunt’s end. The Kamp Ranch Limestone is exposed very nicely at the site, as well as meters of shale beds above and below it, making a short study of the successive stratification obligatory. FIG 1: The roughly 38 cm (15 inch) thick Kamp Ranch jutting out amongst the soft shale and clay above and below it. The clouds foretell the showers to befall us. (ID request incoming)
