texaswoodie Posted October 10, 2009 Share Posted October 10, 2009 I've looked at Mos bones until I'm cross-eyed and cannot ID this bone. Maybe someone with a clue has a clue. Looks like a shark gave it a love tap Then there is this jaw looking thingy. Is that a couple of tiny teeth I'm seeing? And my question is: The marine animals at NSR are about 65 MYO more or less. But there are also mammal remains to be found. What is the age of the mammals? Thanks for any input! Link to comment Share on other sites More sharing options...
MikeD Posted October 11, 2009 Share Posted October 11, 2009 Those are cool. Wish I could help more. Those are teeth on the jaw looking thingy. I would guess reptilian (although I might be wrong). As far as I know, mammals in the NSR are Pleistocene and recent (wild and farm animals). Link to comment Share on other sites More sharing options...
tracer Posted October 11, 2009 Share Posted October 11, 2009 the top piece has joint articulating surfaces on it. at first glance it looked verty, but i'll go look at other possibilities and might or might not get back to you. the jaw is a jaw with broken-off teeth. mosasaur. all i've heard about the reworked mammal stuff is that it's pleistocene, and then of course you'll find recent stuff mixed in - turtles, cow, horse, pig, etc. edited to add - i don't know - maybe the proximal end of a humerus or something. if it isn't vert, then it seems like it should be where an upper appendicular bone joins the body...

texaswoodie Posted October 12, 2009 Author Share Posted October 12, 2009 Thanks for the info! The Mos jaw must have been an early small one or a juvenile. That is some tiny teeth next to the 2 inchers I've seen. Link to comment Share on other sites More sharing options...

That is some tiny teeth next to the 2 inchers I've seen. well, yeah, either that, or i'm totally wrong, which is the other distinct possibility. it's not that there weren't other very toothy cretaceous fish. but the jaw of that is fairly massive-looking and the broken-off teeth look mos-ish, except for the unusual small size, so what the heck.

tracer Posted October 12, 2009 Share Posted October 12, 2009 now i'm second-guessing myself. i always do that when nobody jumps on the post and screams, "you're WRONG, tracer! WRONG! WRONG! WRONG!" )what's with the freakin' capital letters? did somebody hack my account? is this really me?( maybe it was a pachynondermrhizodus or something - look at the upper right drawing on this link ok, what other than pachy, enchodus, and x-fish was large and toothy and mosasaur-mimicking back when the north sulphur interior seaway was teeming with sea monsters? can you just freaking imagine? sailors back then probably had eighteen life-boats strung all around their big boats in case they started sinking. wonder if anybody ever fell in and had to watch the giant sea monsters fight over them before they got chomped.

LanceH Posted October 12, 2009 Share Posted October 12, 2009 (edited) ok, what other than pachy, enchodus, and x-fish was large and toothy and mosasaur-mimicking back when the north sulphur interior seaway was teeming with sea monsters? This PDF has a list of some of the fishes known from the Western Interior Seaway. Annotated checklist of fossil fishes from the Smoky Hill Chalk of the Niobrara Chalk (Upper Cretaceous) of Kansas Other large and toothies could be plesiosaur, pliosaur, ichthyosaur.

Yup, it does look very similar. Got a link to more drawings like that? Oceans of Kansas has some, but I like the close view this one has. Link to comment Share on other sites More sharing options...
JohnJ Posted October 12, 2009 Share Posted October 12, 2009 texaswoodie, do you have a side view pic? Sometimes the bone texture can assist an ID...I'm leaning toward fish. The human mind has the ability to believe anything is true. - JJ Link to comment Share on other sites More sharing options...

JohnJ Posted October 12, 2009 Share Posted October 12, 2009 Thanks. Those views look more like the flaky texture of Cretaceous fish bone. In addition to the OOK pics of Pachyrizodus, below is a pic of a partial Xiphactinus maxilla (4-5" long) that have similarities to your find. The human mind has the ability to believe anything is true. - JJ Link to comment Share on other sites More sharing options...
Xiphactinus Posted October 12, 2009 Share Posted October 12, 2009 That's either a Xiphactinus or Pachyrhizodus jaw fragment. Nice! If the teeth are all the same size, I'd go with Pachy...different sizes, X-fish. From what I can tell from the photo, it looks like Pachy. Link to comment Share on other sites More sharing options...
tracer Posted October 12, 2009 Share Posted October 12, 2009 wow - i just kinda squeaked outta that one, sort of. i've been rong too much lately. reminds me of the bisony deer debacle a while back. thought i'd never live that one down...OOPS, um, look! halley's comet! <pointing at the sky as he snoopy moonwalks out of the topic> Link to comment Share on other sites More sharing options...
texaswoodie Posted October 12, 2009 Author Share Posted October 12, 2009 (edited) Wow, very cool. The two that are showing are about the same size. There is a socket without a tooth that looks a little larger. This started me looking through my bone box and apparently I have several fish bones and didn't know it.

CreekCrawler Posted October 12, 2009 Share Posted October 12, 2009 Here is another one to compare it to also..At first I thought it was a Xiphactinus,but my bubble got popped when X-man ID'd it as a Pachy.It came from the same river as yours Curt. If I remember correctly JohnJ ID'd it as fish due to the flakiness of the outer skin on the bone.I know there is a word for the outer skin that is left on a fossilized bone????

texaswoodie Posted October 12, 2009 Author Share Posted October 12, 2009 Awesome jaw John! You always find the neatest stuff Barry. I'm going to have to rub shoulders with you more often. Link to comment Share on other sites More sharing options...

Thanks Curt,but if you really want to find the goodies you need to rub shoulders with JJ and DW. My neat finds don't come as often as theirs You are however welcome to tag along anwhere that I go.Of course as long as you bring me a cabachon for each outing :lolu: Link to comment Share on other sites More sharing options...
