Basal Atco

Austin Chalk/Eagle Ford Basal Atco fish conglomerate zone of North Texas

On a recent outing with my 7 year old grandaughter we were at a construction site where the the basal Atco was once exposed at ground level. They had bulldozed it all and this interesting slab of flagstone was laying there. The fish conglomerate was laying about here and there where you could pick it up by the hand full and sift it for tiny teeth. She with her short close to the ground stance and fresh eyes could really spot those itty bitty teeth too.

Construction exposes it then buries it. This site had produced a number of smaller sharks teeth and some nice ptychodus. I found one of my coniasur verts there. Now I guess it's pretty much done...but we will see!!

would love a slab like that at my place, something special about a moment in time preserved like that

I've got a backyard full of it, nothing that large though. I'd have loved to have gotten that one home and I even thought about asking them to load it in my truck with some of their equipment...but alas it's gone. I imagine it got buried.

That is a very cool slab; looks like an overturned 'positive', what with the raised worm tracks.

I figured they were wave ripples

Nice. It is a shame most of those construction sites around there are buried up now, isn't it? But I suppose what construction giveth...

Oh, they definitely are! I refer to what look like 'worm tracks/burrows', raised here and there on the rippled surface.
