Lake Diefenbaker Trip - Bearpaw Formation
Norki posted a topic in Fossil Hunting TripsSo 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)
fgiarro posted a topic in Fossil PreparationHello- 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
Arcadia Park/Britton Gastropod/Ammonite?
Heteromorph posted a topic in Fossil IDOn 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 min

Bow River Alberta fossil trip May 2018
JustPlainPetrified posted a topic in Fossil Hunting TripsIt has been two years since I last went on a fossil hunt along the Bow River. Permission from landowners is a must but there is also lots of public land affords river access. Lots of climbing. 250 feet of elevation might not seem like much but it sure takes its toll when you load a large partial ammonite into your pack. Two trip; the second one just to make sure there wasn't a piece in the water that I could see. I actually climbed high to an exposed concretion and, knowing it wasn't a fossil, I broke it and watched it bounce and plunge into the river. Now I know just how far out the rest of t
Annual Rutgers University Geology Museum Open House
jpenn posted a topic in A Trip to the MuseumThis 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 a

One Giant Huge Ammonite !!!
RJB posted a topic in Fossil PreparationHere 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
Been a long time since Ive seen this BEAUTY!!!
RJB posted a topic in Member CollectionsThis 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
A Real Puzzle this was !!!
RJB posted a topic in Fossil PreparationThis 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 togeth
