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 past weekend was the 50th annual Rutgers Geology Museum open house, which was an excellent opportunity to attend guest lectures by professionals and also a chance see the museum's collection. The event was very well attended, and in between lectures (the lecture by Dr. Isaiah Nengo on his work with Nyanzapithecus alesi was excellent) seeing the museum was a hurried, crowded affair. The museum building is a tall 19th century structure with many large tall windows, so on this sunny Saturday sun glare on the glass cases was unfortunately a real and unavoidable problem. Nevertheless, I made an effort to get some photos of the museum to share with TFF. The Mastodon is a Salem County NJ find. Particularly exciting for me as a huge fan of Phytosaurs was seeing their specimen of Rutiodon manhattenensis, which despite its specific name was found on the New Jersey side of the Hudson. Yet another example of New York stealing New Jersey's credit! Hidden in a corner (it was packed in there, things crammed into corners to make room for tables) was a skull of Mosasaurus "maxmimus" which I'd have loved to known more about since it was apparently a New Jersey find. Alas, no more info than that. Next to it was a cast of the original find Mosasaurus hoffmanii from the Netherlands, which was neat to see in real scale.

Here is what my son brought home yesterday. Freakin Huge!!! Its missing most of the fragmacone, but it measures 24 inches! I popped off the rest of the rock on the 'top side'. Only took about 5 minutes and you can see that it is a bit crushed, but after talking to my ammonite buddy, he tells me that another ammonite of the right size and the right prezervation that he can make it look whole again. And believe me, this guy is a master at putting two different ammo's together!!! Just might turn out to be a purty dang nice ammonite? Oh, and I saved all the rock that came off this thing in order to put shell material back on. You cant see it, but there is lots of color!!! Gunna be a job though. Once done, it will be in my sons house. Purty dang heavy also!!!! RB

This morning I was moving some of my fossil crab concretions around and tryin to orginize a bit and ran into this Beauty! It had collected a bunch of dust. I had to wash it off even! Now, finally, its in the house. Just wish these pics could do the color on this thing some justice, but im not good at photography. Its got some wonderful purples that you can not see. My son found this many years ago and it took me many hours of prep with lots and lots of sanding and then a coating of some kind of 2 part system, but it came out purty good. RB

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
