Hi, everyone! Got back to New Jersey on Tuesday, after a weekend at Ernst Quarries. This was my second trip to the site, the first was back in 2018. The weather was perfect- not too hot and cool towards the late afternoon. All three days were pretty well booked, as far as I could tell, but most everyone seems to leave by 1 or 2:00. Met a bunch of great people, and I think I had a really good dig. In the first photo, the top section shows everything I found on Friday and Saturday- all but 2 or 3 from the same hole in the "main" area, including a section of leatherback turtle shell (left side, halfway down) and a sea lion tooth (top row, just right of center). The grid is my cutting board with 1" squares. At the end of the Sunday dig, I was checking out a previously started hole out away from the main site, across the road just before it makes a right turn to wind around to the parking lot, and pretty quickly found a nice Hooked White that, at the time, had a nice blue-grey tint to it. Rob told me that it's probably going to be a pretty good spot and let me park right next to it on the following morning. It was pretty darn good. The bottom section of the photo shows what I found on Monday, all from the same spot and without using a sifter. I stopped using the sifter halfway into Sunday- I just used the fan method with the shovel. I stand above the hole and cut away a section so it falls into the pit and then, one shovel at a time, scoop that up and fan it in my discard pile so I can see what's in it. Not as thorough, but you get through a lot more material, and anything big enough you WILL see. Also, my back was killing me from using the hand held sifters on the previous days. I made a previous post showing that teeth from Ernst don't just glow under long wave uv light (365 nm), but they phosphoresce (glow for a bit after removing the light). None of the teeth from the second site glow at all, except for a couple of the more orange-colored smaller ones in the lower right. Some of the teeth have a nice satiny, slightly pearlescent finish. Can't wait to go back!

The specimen was found at Ernst Quarries, Temblor formation, round mountain silt. This reminds me of a ray plate except the plate is somewhat wedge shaped, with very thin teeth (?). One longer “tooth” remains in the matrix. Sorry I couldn’t clean it up better, while attempting to do so, it popped out of the matrix. I hope to glue it back in place to complete the prep, but the risk of further damage may change my mind. This prep has revealed multiple specimens, changing the plan and approach again and again. Nice problem to have,right? The last photo shows one of three larger specimens in the original matrix. I will seek additional IDs and prep advice in separate posts.

Hi people, I'm visiting the ernst quarries on Friday June 5th 2020. First time there, I'm from Spain so it will be an intensive and exciting day. If someone from the forum joins just let me know. Cheers!!

I would like to try to prep a whale vertebra I found, but I have a few questions before diving into the preservation part. My questions come in 2 parts: Paraloid suggestions and matrix removal questions. Paraloid: For something this big, should I attempt to find a container and dunk the whole thing in the paraloid solution, or should I use a brush to go around the whole surface? Any suggestions for the ratio of paraloid to acetone? 1:10? 1:20? I've read different ratios thrown around, but I'm not sure what is best for which situation. Matrix removal: There is a large section of material on the under side of the vertebra that I'm unsure about removing. This rectangular section seems to be much harder than the rest of easily removable soil. Even though it transitions from reddish to tan in color, it is all the same hardness. Should I even attempt to remove it, or just leave it? It's clearly not part of the original vertebra, but I'm not sure what it even is. Thanks a lot for any help and/or suggestions!

Earlier this summer I had a chance to dig at Slow Curve at Ernst Quarries. A few teeth were found along with a small dolphin vertebra, but the best find was this large whale(?) vertebra I pulled out as the rain clouds were quickly approaching. From my internet research, I believe it is a whale lumbar vertebra, but that is all I could determine. Whatever it is, I feel lucky to have found it and want to know as much as I can about it! Is there any chance to pin down anything more specific about this piece, such as species? Ideally, I would like to reconstruct the broken processes and make a display. Are there any collections of images for whale vertebrae that could also help with identification? (I couldn't find any good sources while searching) Am I correct in thinking the two parallel broken processes in the second image were the top (dorsal?) of the bone? Is it possible to tell which way the bone faced toward the head and tail originally? I appreciate any help that you guys and gals can provide! Each of the photos has a US quarter, Euro, and centimeter scale for reference. (I first tried photos with lights on both sides, but then the shape of the vertebra was very difficult to see.)

Epiphysis is the rounded end of a long bone, at its joint with adjacent bone or bones. Epiphysis that are found are usually from a juvenile mammal since they aren't joined to the main bone yet....Most call them "cookies". -
