Making a shark tooth/ray shadowbox - need to confirm species


Incognito Rockhound

Recommended Posts

Hello everyone,

 

I am making a shadow box for my office; before I start doing the final groupings by species and attaching said groupings to the shadow box, I could really use some help. 

 

I have made my best educated guesses (using Jayson’s website for references), but since I am a novice, I know I’ve made several mistakes.  

 

Will you you please take a look at the attached pictures and let me know if I guessed correctly? If not, will you please let me know the correct answer?

2: I think you're correct

3: I think you're correct

5 and 6 are Hemipristis. Snaggletooth shark

 

Thank you! 

 

Glad I am on the right path - still much to learn!

When you discuss shark and ray teeth it is best to use the scientific names which are standard worldwide.  Common names are not standard, and a single species can have a number of different common names that conflict with other species.

 

 

In this picture the tooth circled in red is a Carcharhinus sp. tooth.  The rest of 2 & 3 are either Galeocerdo sp. or Physogaleus sp.

In this picture you could have a mixture of teeth.  The teeth circled in red in 8 can be Aetobatus teeth from the upper plate or possibly Aetomylaeus teeth.  The rest of the teeth in 8 could be a number of genera like Aetomylaeus, Myliobatis or Rhinoptera.  The one tooth in 9 on top is definitely an Aetobatus tooth from the lower plate.  The other could be an Aetobatus tooth from the upper plate.

Thank you for your input Marco.  As I stated above, I still have much to learn so all input is greatly appreciated!

 

I will do my best to use the scientific names from this point forward; I ask that you bear with me as I learn.  When it comes to shark teeth and rays, my ability to properly identify and articulate what I am sharing is comparable to a baby learning to walk; I am at the very beginning - somewhere between rocking back and forth and starting to crawl.  I will probably fall over on my side several times before I am crawling full time :)

 All teeth in group to have both distal and mesial serrations.

I just noticed that I forgot to add clarifying info to this statement - the group I am referring to is 2.

 

My apologies for the omission.

I'm interested to see what others call #1. I know it is some type of Mako, but I'm not sure which. I can narrow it down to I. retroflexus, I. oxyrinchus, I desori, or C. Hastalis, but I'm not sure which. I'm leaning towards I. oxyrinchus.

#1 is a lower tooth from Isurus or Carcharodon. Lowers are much harder to differentiate in this group.

#6 looks like a Carcharodon hastalis. Does not look like a Hemipristis.

What are your thoughts on 4 and 7?

4 matches with lemon (Negaprion sp.).

7 is neither angel (Squatina sp ) nor thresher (Alopias sp).  Possibly a worn Galeocerdo  sp. (Tiger).
