Matoaka Beach Gold

[Phoenix814]

Some of the awesome finds from 2 days worth of hunts at Matoaka Beach. I have no clue what the vertebrae belonged to (I know it’s not a shark). I believe the large bone in the back is whale, just don’t know what part. Lastly, if anyone has any information on what the shark teeth are exactly please let me know. I believe the big one is a mako, the long pointed one may be a lemon, and of course the snag for tooth. If I am incorrect please let me know! Looking forward to going back and finding more!

Looks like a fun day out at the beach. The Ecphora is spectacular!

 

For a better chance of identifying the smaller shark teeth try a closer photo detailing just those (the scale helps). It'll be easier to determine an ID when there are more pixels to see.

 

 

Cheers.

Thank you!

The smaller teeth need closeups but the big one is a mako. Nice finds!

Other members with more experience will chime in on the IDs for these teeth but it appears that they are:

 

#1: Sand Tiger shark (Carcharias sp.)

#2: Bull/Gray/Reef Shark (Carcharhinus sp.)

#3: ??? seems to be a more lateral/posterior tooth due to the slanted angle

#4: Extinct shark similar (possibly related) to modern Tiger Shark (Physogaleus contortus)

#5: Difficult to see but possibly tiny Snaggletooth Shark (Hemipristis serra)

#6: Mako/White Shark ancestor (Carcharodon hastalis)

 

Looking forward to other members in the local area refining this initial ID pass. @Walt

 

 

Cheers.

I agree with digit on the id’s, but the thick root makes me wonder about #1.

[HemiHunter]

#1 looks like a lower snaggletooth to me (Hemipristis serra), but I'm not expert like others here.

#1 is indeed a lower Hemipristis serra. 

[digit]

Yup. Looking closer at that one it is indeed a lower Hemipristis serra. Sand Tiger teeth are similarly elongate and curved and usually have a small side cusp on either side of the primary cusp (which are often broken off and missing).

What about cow shark upper for #3?

Nope. Looks like a posterior P. contortus if I am correct. But definitely not a cow shark.

[cck]

Oh yeah I see that now!

[cck]

Kinda like this one?

[digit]

Yup. The curved shape of the enamel crown on that one screams Physogaleous contortus.

 

 

Cheers.
