Texas has had SO MUCH RAIN in the last month! Mushrooms are growing where there are normally NOT mushrooms growing- but that means it has been a bonanza for fossil hunting, needless to say! If you don't mind the mud..... We have had some epic storms, too. 2+ inch hail, crazy lightning, a few tornado scares and amazing clouds. Hail from my house...my poor car. (That's a quarter for scale - 25mm) But EVERYTHING is green and the wildflowers are gorgeous this year! Havn't found anything NEW, but did a couple of nicer examples, which a

From the album: Texas Echinoids, ERose
This specimen appears to match the species C. ovatus which was previously known from the slightly older Glen Rose Formation. This one is from the Bee Cave Member, Walnut Formation, Fredericksburg Group, Travis County, Texas. -
Well, I have to say, not having a full time job due to this pandemic has been extra good for my fossil hunting! I may not be making much of a living, but I'm living it up finding fossils! Fortunately, as someone pointed out to me recently "it seems like Texas is paved in fossils". While this may not be 100% accurate....it's pretty close! Within a gas tanks drive I am lucky to have MANY MANY fossil hunting spots available to me. And when November rolls around (honestly, the nicest month in Texas- mild temps and no Cedar Fever Allergies to contend with) I try to get out as much as possible. And

It was a beautiful day here in Austin and I decided to get a few quick hours in on some local Walnut Formation exposures. Lower Cretaceous. I think I found the largest Coenholectypus planatus I’ve ever seen. It is slightly crushed but would be a full 5 centimeters in diameter. My largest prior specimen was maybe 4cm. Tell/show me your largest of this species.

I have a couple of Coenholectypus from the Glen Rose which have the morphological characteristics of Coenholectypus nanus as described by Cooke, 1955. Some Cretaceous echinoids from the Americas. Geological Survey Professional Paper 264-E, page 96. In an aboral view, the periproct is clearly observed as a notch on the side of the test. It winds around the ambitus and terminates about three fourths of the way to the peristome. It is not Coenholectypus planatus. This is one of the specimens I wish to include in my book on Texas Cretadeous echinoids. However, I am just a little hesitant to
