Hello all! This is a little photo project I've been working on for a while. When I first started Fossil Hunting I was content to collect whatever. Then I was excited about Identifying what I was finding. The education continued and now I work to identify the geological formations I am collecting in and am able to know what fossils to look for in what areas. The Pocket Texas Geology website is invaluable for finding out the formation of a specific area (while not 100 percent accurate, it's pretty good). So I wanted to create a post that would help with Central Texas Cretaceous Fossil Identific

For whatever reason, I used to completely dismiss the Austin chalk as a formation of any interest. I viewed it almost through the same lens that I view the Edwards formation, as if it was some barren uninteresting hinderance that gets in the way of cooler formations. Accidentally finding a large Parapuzosia ammonite in it once changed that a bit, but for the most part I still ignored it... Turns out I was just looking in the wrong places, and had very little understanding of its members. @LSCHNELLE recently explained a lot of it better to me, and so equipped with new knowledge I de

With the end of the semester approaching, school has picked up and I have been too busy to embark on many adventures. When my schedule finally cleared up one afternoon following a brief rain in Austin, I jumped at the opportunity to do a bit of exploring. One of my goals right now is to check out new parts of the creek I hunt on. Scanning through my list of potential spots, I decided to try and be the first one out to a very promising location. Like my previous hunts, this place ran through the Ozan formation, so my expectations were set on some nice Cretaceous specimens as well as the usual n

I found this rock in Austin, TX in Waller Creek next to an exposed outcrop of the Maastrichtian (Late Cretaceous) Austin Chalk. I’m wondering if it’s a mosasaur vertebra or humerus? Several mosasaurs have been found in creeks nearby, and the wavy pattern in the rock reminds me of fossilized bone. I’ve included three photos of the rock that I found in Austin, and a photo from Otero et al. (2016) of a Maastrichtian mosasaur right humerus (scale bar = 50 mm) that looks similar.

Can anybody ID what this is? I found this several years ago in the North Texas creeks. It has some spots on the top and broken shells mixed with it. Could that round dark spots be coral or bryozoans?

Inoceramids were very large clams that are abundant in the chalk. Often you only find portions like this, with telltale calcite prisms (seen here as vertical lines) which composed their shells. -
From the album: Austin Chalk
The Austin chalk as its name suggests is primarily composed of chalk beds with interspersed marls. Here you can see the transition from chalk to marl (light towards the top, grey towards the bottom). I at first hoped this was the Eagle Ford contact horizon (which is a shale with cool shark teeth), but alas not. -
Austin Chalk Formation, bivalvia found near Hillsboro, Texas 180 MM in length and 130 mm width. -
From the album: Austin Chalk
Vertebrates are generally rare in the Austin chalk, especially in the upper portions. Since this was not found in the formation, I can't say for sure where in the column it came from. Based on the surrounding exposures, it likely came from the upper Austin chalk which is very unusual and warrants further investigation upstream... -
My family and I love to explore creeks on the weekends. We've found many fossilized oyster shells before, but this is by far the largest specimen to date.

My next door neighbor, Jim, was kind enough to take me to my cataract surgery today, and after I took him out to breakfast, we had a little time to kill before my follow up appointment. On a whim, I suggested an Austin Chalk creek stomp since current drought conditions wouldn't result in muddy shoes. It was a fortuitous move, as the creek outperformed expectations. The bedrock there is slow to erode, so I've rested the site for a few years. We got 2 nice Eutrephoceras nautiloids. The one that Jim is posing with below is now cut to a nice pedestaled display piece wh

In Central Texas you don't have to go very far to find fossils. But the Austin Chalk Formation is a little tricky finding good spots which are fairly fossiliferous. Fortunately, the Paleontological Society of Austin visits a couple of good spots and the fossiling was pretty decent this time, because we've had some good rains! This particular creek is really lovely, too....white limestone with green ferns and even some Mustang Grapevines! Although it was a hot day (as per the usual in Texas Summertime) the creek was at least shady and a bit cool and it felt great to stick my feet in the water t

I didn't even realized they found the Mosasaur at this Garland Duck Creek (creek, not a formation), but in the Austin Chalk formation. I live just two miles from location and walked on this creek several times. Creek is several miles long. This was a rare find. Here is the follow up video.

While visiting family member in Central Texas, I couldn't resist stopping by roadcut next to the Interstate 35. Road crews are adding lanes so they were cutting lots of shoulder next to the highway embankments. I'm finding Inoceramus and giant clams measuring about 3 to 4 feet across. I have also seen similar giant clams in the DFW Austin Chalk layer, but this one looks almost intact.

This is my best find to date and I would love your input and observations... I found this specimen in McKinney Texas (suburb north of Dallas) in late 2020. While my wife my was antique shopping, I went to a local housing development to look for fossils. To my surprise I found this beautiful tail fin in the Austin Chalk formation. It was in about a 300 lb boulder, but it was well worth the effort to salvage it. I have returned to the area to search for more sections, but after hours of searching I haven't found anything new. In the original boulder, I also found a suspected scale and a si
