KimTexan Posted January 29, 2019 Share Posted January 29, 2019 I’ve never posted a vertebrate fossil of the month so bear with me. Date of Discovery: January 12, 2019 Scientific and/or Common Name: Bison sp. Most likely Bison bison. Geologic Age: Pleistocene State: Collin County Texas I actually discovered parts of the skeleton in June 2018, but thought it was a cow. 1/12/19 I found out it was a bison and immediately drove back out there to see if any of it was still there. 7 months later, numerous flooding events. This is what I saw when I arrived. I thought it would all be washed away. The skull, thoracic vertebrae on left and cervical vertebrae on right and a femur, tibia and radius further to the right in the bank. Cervical vertebrae in situ Fully articulated left left rear leg. Pelvis and femur all the way down to the phalanx (hooves). Tibia on right. Metatarsal straight ahead and foot on the left. Sorry for the blurry pic. Most of the bones excluding the skull, 3 vertebrae, 2 scapula and a number of rib pieces and lots of bone fragments. Many to the vert spinous processes. Shoot! I forgot to put the mandible in the pick. You can see it and more in the link. Also, one of the femurs appears to have canid ( Canine) bite marks that ripped of the left knee cap and part of the condyle. So predations marks. Recovered Skull with mandibles and teeth 2 femurs 1 tibia 1 metatarsal with associated feet and tarsal bones plus a number of other lower leg bones for right leg 2 humeri 2 radius with ulnas 2 metacarpals 2 scapulas Pelvis 11 thoracic vertebra 5 lumbar vertebra 6 cervical vertebra including atlas and axis 3 caudal verts might be classifying one wrong. Sacrum A number of rib fragments and 1 whole rib. I am missing the tibia and a metatarsal. I think I may be able to find those and some feet bones. LINK to one of the topics about this find. That’s my entry. It’s the find of a lifetime for me. 13 Link to comment Share on other sites More sharing options...
Al Tahan Posted January 29, 2019 Share Posted January 29, 2019 @KimTexan that must have taken forever cleaning and organizing all those bones!! Labor of love . Nice job!! Link to comment Share on other sites More sharing options...

Nice job!! I still have a lot of work to do. I think cleaning the mud off took me about the same amount of time as it took to extract them. I must say though they’re so easy to clean compared to other stuff I collect. I need to start stabilizing them and gluing them back together. 1 Link to comment Share on other sites More sharing options...

I finally figured out this is a Kainops invius trilobite (no pun intended haha). I found this on January 9th 2019 and prepped it on January 26th 2019. Kainops invius Geologic formation: Bois D’Arc Formation Geologic age: Lower Devonian Location: Clarita, Oklahoma (Theisons quarry) Wow! it is a beauty and nice prep work. 1 Link to comment Share on other sites More sharing options...
Mike from North Queensland Posted January 31, 2019 Share Posted January 31, 2019 (edited) Here is a shark tooth I found this month while sieving matrix collected last year. This one I am not sure if it is pathological or positional as the side cusps are not sharp and pronounced as in previous specimens and quite rare at the best of times. My understanding is this is the earliest example of this species so an interesting find. Date of discovery - 11-1-19 Scientific name -Johnlongia sp Geologic age - Albian cretaceous Formation - toolebuc Site - Central Queensland Australia Longest side is 6 mm or 1/2 inch so quite small Mike Edited January 31, 2019 by Mike from North Queensland dimentions added 9 Link to comment Share on other sites More sharing options...

digit Posted January 31, 2019 Author Share Posted January 31, 2019 Nice shark tooth. Very unusual shape compared to most modern day shark teeth. What's the overall length on that tooth? Hard to judge with no scale. Cheers. -Ken Link to comment Share on other sites More sharing options...
FossilDAWG Posted January 31, 2019 Share Posted January 31, 2019 Nice tooth! Just a note for US readers: the rest of the world rather logically enters dates as day/month/year, so Mike's tooth was collected Jan 11 2019, and so is "in date" for the contest.

That and our incomplete acceptance of the metric system have been a source of personal shame at a global level for decades. For dates, I personally use YYYY-MM-DD as an unambiguous date format that sorts better on computers as a bonus. Well noted that this lovely specimen is "in date" and not the result of Marty McFly time travel (which would allow some stunning fossils to be entered if used properly). Cheers. -Ken 2 Link to comment Share on other sites More sharing options...

Don US military generally writes dates as 31Jan19, so they are on the same page at least. 1 Link to comment Share on other sites More sharing options...
