Recently acquired a Triassic Theropod Dinosaur Tooth from New Mexico, USA

 

Coelophysis bauri tooth

 

Location: Bull Canyon Formation,

Norian, Upper Triassic,

San Miguel County, New Mexico, USA

210 Million Years Old

 

Obtained from Palaeontologist Byron Blessed

 

Below are some sample photos, I am looking around for a small device in order to try magnify the serrations on the tooth as there are so many and it is very hard to count the number per mm. I have read the books and journals on Coelophysis bauri that were linked on this forum previously and they are so interesting! Will try to post some close-ups of the serrations, the other side of the tooth and the bottom of the tooth soon.

 

 

Wiki Link: https://en.wikipedia.org/wiki/Coelophysis_bauri

Journal is called 'Acritical re-evaluation of the Late Triassic dinosaur taxa of North America'

Nice little tooth. :)

Thanks, I have a separate set of 25 of these teeth coming from fossilsource (Larry Martin). Larry Martin was a Renaissance paleontologist, with a primary interest in avian fossils and evolution, who practiced his trade at the University of Kansas (KU) for 40 years. Larry unfortunately passed away in 2013.

 

The teeth were originally displayed on an original oil painting of Coelophysis. The teeth include various positions in the dentition, anterior, posterior, upper, lower (not all associated but found on the same layer). All 25 teeth were offered to obtain together.

 

They were found in upper Triassic age deposits (Norian), in the Bull Canyon Formation, in Quay County, New Mexico. The largest teeth measure approx. 3/16" (5mm) in length for size perspective.

 

You will also see pictures that show the area these fossils were found.

You are mixing up two different people.  Larry Martin the prominent paleontologist of the university of Kansas did pass away in 2013.  However, there is another Larry Martin who is a fossil dealer (fossilsource) who currently lives in New Mexico and is a member of this forum.  

Oh I see haha my bad! I had a feeling I was considering he passed away in 2013! I still think the 25 teeth are the real deal though.

 

Do you know what his account is called on this forum? Thanks!

I believe its fossilsource.  Coelophysis teeth can be very difficult to identify so I would have a careful look at those teeth even the one from Byron since the distal side usually has some curvature to it.  Far from an expert on Triassic material but has Coelophysis been recorded or described from the Bull Canyon fm?  I ask that because of the NM geological society 2001 faunal listing is not showing C. bauri.

I think Coelophysis bauri is only described from 'Ghost range' (Rock point formation) and the Chinle Formation.

@Troodon Teeth conforming to Coelophysis have been found in Bull Canyon Formation, according to the Fossilworks database > http://fossilworks.org/?a=collectionSearch&collection_no=57071

I have also seen sellers label their Bull Canyon teeth as cf. Coelophysis bauri

@-Andy-  I had seen that but its not really clear with  Bull Canyon material .  The 2007 study "A critical re-evaluation of the LateTriassic dinosaur taxa of North America"  by  Sterling J. Nesbitt et al. assigns most of that type of material from the Bull Canyon as Coelophysoidea indet., Coelophysis sp. or  Archosauria indet.  I really dont think most suppliers know what they are selling simply because the people who study this are unclear how to assign the material.

Coelophysis bauri tooth, Location: Bull Canyon Formation, San Miguel County, New Mexico, USA (Obtained from Palaeontologist Byron Blessed) - Part 1

 

As Troodon stated in an earlier post, it is very difficult identifying this tooth as Coelophysis bauri but for those that are interested below are some close-up pics of the tooth I posted in the first post. The close-up shots make this tooth look big but it is tiny and it was extremely hard for me to take pictures of the serrations through the lens. Thankfully they have built in led lights on either side of the eyepiece which helps bring out the colour and the serrations of the tooth. I hope to get better equipment in the future with greater power of magnification for better visualisation but this is what I have currently.

 

Equipment: Inspectacles from 420specs.com Model 1 - Item #42-0247 - Fixed-Focus High Mag Kit Monocular. The focus is fixed at approx. 1.5" from the lens..Twenty times Magnification....If anyone can recommend a magnifying glass with stronger magnification then please let me know, this will be extremely useful for smaller teeth like this. Close-up pictures for the 25 teeth mentioned in the second post are also in the posts below. Enjoy!

My ruler shots in my photos are pretty bad, it was just for me to count the number of serrations per mm when looking at them through the magnification glasses and some for a scale as to the size of some of the teeth. From the above photos the serration density is about 7 serrations per mm on the inside.

As Troodon stated in an earlier post, it is very difficult identifying this tooth as Coelophysis but for those that are interested above are some close-up pics of the different varieties I have obtained for this so called coelophysid dinosaur. The close-up shots make the teeth look big but they are tiny and it was extremely hard for me to take a picture through the lens of my spectacles for magnification. Thankfully they have built in led lights on either side of the eyepiece which helps bring out the colour of the teeth and the serrations. Equipment that I used to magnify teeth is below. I hope to get better equipment in the future with greater power of magnification and visualisation but this is what I have currently. Enjoy!

As mentioned earlier,the focus for the above is fixed at approx. 1.5" from the lens..Twenty times Magnification. The goggles adjust vertically and individually. They can also be moved laterally on the frame or even removed. The bright L.E.D. lights turn on and off individually and they are mounted on a horizontal swivel. This really helps to scan for those interesting details with ease. One goggle can be used at a time alternating eyes. They are not binocular. At last, a hands free helper that adjust to my needs...

Thanks and no problem! Took me a while today to take photos of them all! Just wish I knew more about this wonderful dinosaur!
