The Very Long Very Hot Very Dry Summer

Less than half of the garden is occupied by plants this summer, so we have lots of opportunity to work on the beds. As you can see from this picture, we can locate areas of white chalky limestone soil we call caliche. It is very dense and can be dug out in in chunks and layers. 

The other day, I was digging some caliche and out fell a fossil! It was embedded in the layers and had not been exposed to the air for many years. I looked in my Texas Fossils by William H. Matthews III and found that it is called a Texas Cretaceous Gastropod. It is actually an internal mold of the shell of an animal which was on the ocean floor during the age of dinosaurs.
