Cool paper for those interested in the Ceratopsian, Pachyrhinosaurus Darren Tanke "This was discussed some time ago and of interest to several artists awaiting the "new look" of Pachyrhinosaurus perotorum. Paper on revised frill morphology of Pachyrhinosaurus perotorum by Tykoski et al., 2019 here. Well, it turns out the "new look" is much like the "old look" in other pachyrhinosaurs; the frill looks much like that in P. lakustai and that speculated on in P. canadensis."

I found a few fossils while on a hunting trip. The fossil Im most curious about is in the first 2 pictures. Any Idea what it might be? Third picture seems like obvious marine fossils.

Hi everyone- I have a juvenile mammoth tusk that I would like to learn how to stabilize and restore. The problem is I have (almost) no idea how to even start! The tusk is fully dried out, but it’s split down the middle. I need some advice! Here’s what I know has to be done: 1. Clean the outside and inside as much as possible without using water- any suggestions on what to use? 2. Superglue the two pieces together and use hose clamps to hold the two pieces together- any suggestions on glue/method? 3. Fill gaps/cracks with epoxy- any suggestions on a good type? 4. Sand sand sand! 5. Beyond this point I’m not sure- is there some sort of protective varnish people use? I’m sure I’m missing about a dozen crucial steps here- I have literally never tried anything like this before, so any advice would be greatly appreciated. I posted some photos of the tusk, and I will post photos of progress! Thanks everyone.

Where are mammoth fossils in Alaska found?
-
Hello forum, I hope this is OK to post here. I haven't been on the forum much for the last couple years, since I started graduate studies in archaeology, but I have a mystery I think the FF is uniquely qualified to solve. At the Burke Museum at the University of Washington (Seattle, USA), in the collections is a Yup'ik pouch that is covered with a very small bone (4mm x 1-2mm) used as a form of decoration. The bag originates from SW Alaska. The elements appear to be bones, but maybe shells or teeth. Some extremely knowledgeable individuals have been stumped by this so we're trying a little crowdsourcing. Any help or suggestions would be appreciated. I've attached one photo of the elements, but there are a bunch here: https://photos.app.goo.gl/yJdKozUxGd2uNmar1 Thanks for your help! Dave

Any spot suggestions would be greatly appreciated! Thanks guys!

Hi, all. Total rookie here. I found this on the beach of an island in Alaska's Inside Passage several years ago and have often wondered what it is. There seem to be many genuine experts here, so I'm grateful for any help! It's strongly curved on one side of its cross-section and much flatter on the other side. Thanks!

I got this off eBay as an impulse purchase. It was described as a mammoth bone from Alaska, but I don't know what bone. What am I looking at? Thanks, Matt

Mammoth Tusks, Stable Isotopes, and Diet, Kikiakrorak River, Alaska

I work at a small placer (gold) mine in the interior of Alaska, and we routinely find mammoth ivory. Sometimes just small pieces, sometimes complete tusks. I have purchased one from my employer, and try as I might, I have been unable to find any information on curing, or drying, the tusk before treating with butvar-76 or similar. This tusk is over nine feet long, weighs 85#, and is a beautiful specimen from a mature female wooly mammoth. The bark is a rich mahogany color, mottled with blue and ivory patches. It is obviously worth a small fortune, and I would like to preserve it as best as possible. Other tusks I have seen, will crack and deform as they dry. I want to minimize this as much as possible. I have heard of techniques such as banding with hose clamps, wrapping with burlap and keeping moist, even burying for a period of time, or a combination of these. What have others done with large tusks? How much moisture is acceptable before treating with acetone and butvar-76? Will the solution draw out moisture from deep inside the tusk, or will that water remain trapped there? This one has been out of the ground for less than two weeks. Thanks for any help! Here's another, my tusk is the one in the foreground.

Found this on the beach today. Located in Nome, Alaska, right on the Bering Sea. No bovines to be found here.

Hello, Found this on the beach here in Shishmaref, Alaska. I have doubts that it is terribly old, but then again, there are fossils found here quite often. It's just that the location...seems like someone would have picked it up by now. I found it right at the head of one of the main beach access trails. It is heavier than I would expect of regular bone of this size, though, and it is very hard. Any thoughts or suggestions? Thanks!

Hi. I'm new to the Forum, but would like some opinions about this object I found here in Alaska. It was found in a tidal creek in an estuary in southcentral Alaska. The estuary surface is a mix of gravel, mud, and glacial silt. I've shown this to various local experts, and most think it is some kind of broken fossil, but a few think it isn't a fossil at all. Any thoughts would be appreciated.

Hello everyone, I need some help identifying this bone/fossil, which was found in the Yukon river delta (near the sea) in Alaska. It seems to be rather dense and heavy. The white inner core feels chalky and is detachable from the outer light brown portion. The light brown portion feels smooth. There is a concentric zigzag pattern featured in the cross section. Any input is appreciated! Sincerely, Jay

An article regarding the discovery of a new T-rex relative from Alaska: http://www.science20.com/news_articles/nanuqsaurus_hoglundi_alaskas_pigmy_t_rex-131592 The timing of the description of Nanuqsaurus surprised me, but it's no surprise that N. hoglundi shows that the diversity of Edmontonian tyrannosaurs was greater than previously thought, given that Albertosaurus and Nanuqsaurus lived about the same time and belong to different subfamilies of T. rex. The discovery of Nanuqsaurus also lends support to the hypothesis that the ancestors of T. rex emigrated to North America from Asia via Beringia. The article describing Nanuqsaurus is as follows: Anthony R. Fiorillo & Ronald S. Tykoski (2014)A Diminutive New Tyrannosaur from the Top of the World.PLoS ONE 9(3): e91287.doi:10.1371/journal.pone.0091287http://www.plosone.org/article/info%3Adoi%2F10.1371%2Fjournal.pone.0091287
