Brownie’s Beach bone fragments ID

[KimTexan]

I was in Maryland last week for a work conference. After the conference finished on Friday I headed out to hunt at Brownie’s Beach.

I found a lot of little stuff. Nothing big. Anyway, many of the bone fragments are chunkosaurus. But I think these may be identifiable.

I have put them in 2 rows of 4 each.  

Row 1 are 1-4 left to right.

Row 2 are 5-8 left to right.

First pic is top side. 2nd pic is the bottom.

 

 

1. I think could be a fragment of vertebra, maybe where the spinous process attached.

2. Maybe a piece of turtle shell?

3. A scute from a turtle or something.

4. Possibly a rib fragment. One end tapers pretty thin and it has a curve to it.

5. Is a mammal vertebra 

6. It may be nothing. It is very hard and may just be a phosphatized piece of something. It has a bit of texture of eroded keratin or something. I’m guessing it’s nothing, but wanted to ask.

7. Maybe a fragment of turtle shell or bone. The hole on it is curious, but looks like eroded bone.

8. It has an unusual, convoluted surface texture, but from the side it is unmistakably bone. Could it be turtle? My 2nd guess is a fragment of an epiphysis or vertebral disk, but it doesn’t really look like that pattern.

 

I can provide more pics of any of the items if needed.

Thanks for comment or insight. I’ve never hunted this type of environment or formation before so it was all new to me.

Nobody has any thoughts?

@RCW3D, @Shark Tooth Hunter, @Gizmo, @Darktooth, @WhodamanHD Maybe you guys can give me some input.

4 looks more like a leg/arm bone than a rib.

Do not see any identifiable features in these bones.

[Darktooth]

Sorry Kim, I have to agree with Tony.

[RCW3D]

Umm...I've got nothing!

Agree with Tony on the limb bone, 7 is definitely turtle shell, and is probably a piece of a Cookie/epiphysis for 8. 5 is a juvenile odontocete vertebra, and 1 may be a vert of some sort but I’m not sure id go that far. I don’t think 6 is a fossil and the rest are chunkosauruses.

I was looking at pics I took at the museum and it actually looks like a fragment of dolphin radius. That’s pretty cool in my book. Not something I find everyday.

Woohoo!!!

 

This is a pic from the museum.

 

This is #3 up close. I shared it with someone else and they thought it was a scute of some kind too. The lighting is bad because I was in the crummy hotel. I’ll post some closeups of number 2 & 8. I think someone could tell me what kind of animal they came from. They’re pretty distinctive.

 

Top side

Bottom side.

Here is #2

#8 the pattern is so distinctive.

The side view is clearly bone.

 

These are the same side from 2 angles. The bottom looks just like turtle shell fragments. The top is not not just worn down into this pattern of groves. There is a tiny spot where the bone is broken about 3 o’clock.i say top, but maybe the smooth side is the top. It looks very similar to turtle shell except the texture is different than the other shell pieces I found.

Could it be a Trionyx carapace topshell bone fragment. Or Syllomus aegyptiacu?
