May fossil trip: Dinosaur claw and tooth?

[MedicineHat]

I went out for a fossil hunting trip to southeastern red deer river valley in southern Alberta and I found material from tyrannosaur, raptor, hadrosaur, ceratopsian, turtle, croc, and fish. I even found a snail shell fossilized out of ironstone. 

 

I am struggling with the ID on two of my finds. This claw I think might be ornithomimus. But the tip is broken and also very stout. At first I thought it was just broken but I'm thinking it is unusually short. 

The other is a tooth that I have not seen before. After some research I'm guessing Pachycepholusaurus?

Amazing finds! 

WOW! 

I have no idea exactly what any of them are, but that's pretty rare and impressive stuff, i think.

Amazing finds.

Congratulations

Any idea on this claw? It was right under my nose, literally. My buddy got to it first. 

[BadlandTraveller]

Great finds MedicineHat. Any idea the formation?

Thanks Tidgy's Dad! It was so much fun. We had 30 Celsius weather and that is not in this area in May.

These are some great finds... not a bad way at all to start off the summer ... especially fond of those tyrannosaur teeth 

[Troodon]

Nice finds.

The top claw is indeed from an indeterminate ornithomimid.  The tooth is very odd could be a type of Ceratopsian.

I was about to say that claw does look like ornithomimid. Good to see Troodon already confirmed it, as he's got much more experience with those. Nice find!

[Miocene_Mason]

Awesome finds! Love all those Dino parts

It does have that ornithopod look doesn't it

Being the small size of the ornithomimid claw, do you think it indicates a juvenile? 

 

I looked at your post on pachy vs. thesc teeth, so I thought the tooth looked close to some of the specimens shown. You think closer to a ceratopsian?

Yes, totally exciting start to the year. I feel spoiled by Tyrannosaur teeth this season.

This looks like a beached ceratopsian tooth. 

The last photo angle shows the remnant double roots. And there is a prominent median ridge.

 

this tooth would be situated either in the anterior or posterior ends of the tooth battery.

@MedicineHat, the Chirostenotes pergracilis foot claw and the baby Ornithomimid foot claw are nice finds too.

Congrats!

What size is it hard to tell from your pictures and could be juvie, but its also species dependent. I have Ornithomimid foot claws from the Judith River Fm around 3".  The tiny one is a baby like hxmendosa indicated.

I think hxmendosa did a good job showing you why on the tooth.  Pachy teeth are single rooted and more stick shape than wide like yours.   Lots of species it could fit in that area.

Thanks so much for the ID's. My hunting partner grabbed these ones and I was especially curious of the chirostinestes. Claw ID is something I'm trying to learn more about. There are lòts of subtle nuances.

It's 1 1/8" long: missing a little off the tip and base where it meets the joint, so obviously it's size would measure longer. It does not appear to be missing much off the tip, maybe 1/4 inch - 1/2. I have looked at lots and collected one other that is around 2" long. When I compare, this specimen, the length is significantly compressed yet the height and width are not proportionally smaller, only slightly, perhaps 1/5th smaller than my larger claw. 

This difference triggers my curiousity
