So I decided that I would finally make a point of documenting some of these back country field excursions, and made a Youtube channel to keep the videos all in one place. Here's a a rather ordinary extraction of a placenticeras ammonite found the day before we did a little field work with some paleontologists. The GoPro is a fun addition to my kit, and makes it a lot easier to document the actual process of finding and extracting these things in the field. Anyway, I'll let the video speak for itself - enjoy! (click the image to open video link)

Hello- I have a Placenticeras meeki specimen in my collection (see attached pic) and I'm curious to know if the iridescence of its shell can be improved in some way, given its condition- Thanks in advance, Fabio

On Sunday afternoon I went out with Keith Minor to a North Texas site exposing the lower Arcadia Park formation and (possibly?) the top of the Britton Formation (lower Turonian, upper Cenomanian respectively). The hunt almost never happened after various storm cells were menacing us and the high winds were thrusting cranes into sky scrapers and whipping up emphysema inducing dust clouds. Yet, even though everyone around us was getting Kansas blown at them, we were only exposed to the high winds and rain so cold and blown so hard that it felt almost like hail. But that lasted for only a few minutes, leaving the rest of the day to muck around in the Turonian while the winds blew most of the clouds away by hunt’s end. The Kamp Ranch Limestone is exposed very nicely at the site, as well as meters of shale beds above and below it, making a short study of the successive stratification obligatory. FIG 1: The roughly 38 cm (15 inch) thick Kamp Ranch jutting out amongst the soft shale and clay above and below it. The clouds foretell the showers to befall us. (ID request incoming)

This thing sat in a box for quite awhile. It was a concretion that was 'popped' open but broke very badly! There were two incomplete halfs of this concretion with some ammo material on both halves and lots of left over pieces too. About two months ago I took a chisel and did my best to 'pop' off the ammo parts still on the rocks. I then layed out all the pieces in such a way and realized I had a complete ammo. So,,,,, took many many days but kept gluing pieces back together. I really did think about tossing this into the rock pile a time or two. Once I finally had it all put back together I had to start the 2 part putty attack. Then lots of sanding, then a coat of wax. I finished up only one side of this specimen yesterday and called it quits. I just couldn't see putting any more time into this darn thing. Then last night, about 3 am, I started thinking about how all the hard stuff is done, so why not finish up the other side? Plus, I think it may be the better side. And I would end up with a 'Two Sider'. RB
