Another Trip to Big Brook

[hokietech96]

Hi. Went to Big Brook again yesterday. It’s turning out to be a weekly addiction for me haha. It was in the 30s and sunny to start and then ended cloudy with snow. Fun times. 

 

Not sure what everyone else does to keep hands warm while sifting in freezing water. As a runner, I learned a trick to put latex gloves on as you first layer under whatever gloves you normally use. It works amazing. Keeps yours hands super warm. Hope this helps anyone in the forum.

 

Goblin tooth without the root. (Thanks jersey devil)

[Tidgy's Dad]

Nice finds.

Too cold for me, so thanks for sharing.

[aek]

Nice variety. I like the latex gloves trick, I might have to try that. The "no idea" is a gastropod. 

[Darktooth]

I think the last 2 pics are a very worn enchodus fang.

The latex gloves really works well. Thanks for the Gastropod feedback!

Wow. Thanks so much. Kind of scary that I thought it could be nothing. I’m glad I went with my gut.  Also makes me wonder if I missed anything else.  Now I have to google hybondont.

Not certain that's a hybodont fin spine. Can you provide end shots that show the cross-section?

That’s definitely Hybodont spine 

[hokietech96]

So cool. Thanks so much!

Hi. Not to drag this out but how do I tell the difference from saw fish and enchidus? Here is a picture of the other side 

 

 

 

[hokietech96]

Now that I’m looking at this picture it doesn’t look flat enough for sawfish. Haha

[The Jersey Devil]

The difference is clear when both are complete. When broken a sawfish rostral will not have striations and the base will look broken. It’s really a matter of seeing a couple specimens of each and comparing them.

Oh my gosh. Always bring the mystery pieces home. As they say a fossil in hand is better than two in the brook....

[Carl]

I think it could be a hybodont fin spine but I wouldn't give it 100% confidence. Maybe 90%. The boney part is coarser than I'd expect and it's missing any of the enameloid ornamentation. Granted, that could all be because it is so weathered, but this could also be the edge of a bone fragment of many other things.

[The Jersey Devil]

Most definitely not turtle bone. Most NJ items are weathered, that’s why it doesn’t look like what it really is.
