Need help identifying

[Rita__]

Hi everyone!

 

back again with more finds. Figured it’s easier to post more often with less to identify. These were interesting to me. Sorry in advance if they aren’t fossils but I’m stumped.

 

For #3 - I thought it was a piece of a shell at first but when I picked it up, I noticed the two holes underneath. I can’t find anything online that even remotely resembles it.

 

For #4 - I thought it was a pebble at first but I noticed a darker color difference towards the center and it slightly caves in at the bottom. I tried my best to take clear pictures to show the colors.

 

For #5 - at first glance I thought it looked like the root of a shark tooth but it’s so funneled and symmetrical, missing the tooth so it threw me off. I have found many shark teeth that are worn down, either missing the tooth or the root but none in this condition.

 

 

 

 

 

thank you all so much in advance!

My guesses:

#1: Piece of ivory

#2: Hmmm... piece of bone, but that surface texture reminds me of some sort of scute.  Glyptodon?

#3: Definitely not a shark tooth.  Looks like a fragment of the chewing surface of a whale tooth, or maybe some sort of carnivorous mammal.

#4: I'd say probably just a pebble

#5: Looks like a fragment of a bony fish vertebra
