My best woodbine hunt ever (since I started this year, lol), 11 woodbines and one of them is over 7 inches across! The overall condition is better than my 2 prior excursions as well. I’m super thrilled about these. I also found some great pet wood pieces with the appearance of having been underwater for awhile “back in the day.” Any insight into the smaller “critters” is appreciated. I am not positive if one piece is sandstone or pet wood, but I do have 3-4 pet wood pieces (some not shown). The small ammonite in front is a different species than the conlinoceras tarrantense. Woodbine/eagleford border, Tarrant county Texas. My toes went numb walking the creek. I know another hunter who found 7 woodbines at this spot 2 weeks ago (after our biggest rain since Spring) but I guess my eyes were more desperate to spot what he missed

Hi, I’ve recently been searching through some sifted gravel from a creek. I’ve been looking for microfossils, which I’ve had plenty of luck finding. All sorts of marine Cretaceous invertebrate micros are abundant in the creek gravel, as well as the occasional micro shark/fish tooth, scale, and bone fragment. I encountered a tooth that stood out from anything I’ve found so far. It has a conical shape, and is recurved. Something about this tooth seems very reptile-like. Almost looks like a tiny version of a crocodile or mosasaur tooth. The tooth measures 1 millimeter in length. I tried searching the internet for something similar, and have been unable to find something like this. The closest thing that I found was teeth from a jaw of a Coniasaurus that was found in North Texas. Here is the tooth that I found. It’s 1 millimeter from base to tip. The creek is located in Central Texas close to Austin, and passes through sediments spanning the whole Cretaceous geological column of Texas. From the Glen Rose Limestone to the Navarro Group. (~110-66 myrs). What do y’all think of this little tooth. Could it be from a small reptile like Coniasaurus and other dolichosaurs?

The shell of a "foram" (test). It looks like a snail or ammonite, but is actually a marine protist (only found in the oceans).-

Rhinobatos teeth are so small they make me angry Here you see a dozen guitar fish teeth sitting on the face of a dime! The largest is a bit under 1 mm tall. R. incertus has a pointed crown, R. caseiri has no point.-

From the album: Sharks
Just a handful of Cretaceous species, most from North Texas. The sea that bisected North America ~85 million years ago played host to a diverse and burgeoning ecosystem that supported many species of sharks. It was likely due to specialization that allowed these sharks to all live in the same place and time.-

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-

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.-
