Possible Megalodon Tooth ?

[BRONSON]

Hi again guys, I have another of my fossils to show you, I am putting them all in this topic as I am a complete amateur at this and dont want to make a wally of myself mis-identifying something.

I bought this from my same friend a decade or two ago, its not the best example but it didnt cost me much at the time and I thought it was impressive, the stand another friend made for me and I want to get a name plate put on this one also.

I bought it thinking it might be a Megalodon shark tooth, no idea which corner of the world it came from, I actually thought the grey might of been painted on at first until I took close up photos of it.

So experts out there, I have a few questions for you, 

Is it a Megalodon tooth or another species of shark, 

And what it the current and correct latin name for this shark as I read somewhere a while ago that there was some debate about its ancestory and there was two latin names kicking around

Which of these latin names should I use or would you use,

And finally anything else of interest you could tell me about my tooth from looking at my pics,

 

Cheers in advance

Bronson

It is a megalodon. Until recently the classification was Carcharocles megalodon, now it is Otodus megalodon.

And some more,

Wow that was quick, thankyou, so it was previously thought as an ancestor of the Great White, now it is of the Otodus family ( I think I have a tooth from one of those), did the Otodus family die out with the Megalodon then, or does it have any modern decendants ?

Interesting! Just out of curiosity - do you have any papers on this?

I have just found this after a quick search.

I'm looking for an actual scientific paper but thanks.

Latin names are italicized by the way Otodus megalodon

which has no known extent descendants (makos such as the great white being cousins, and I would guess porbeagles and salmon sharks).

@WhodamanHD When you  say "makos such as the great white being cousins," are you referring to the Carcharocles hastalis? If so, C. hastalis was moved into the white shark lineage about 18 months ago and is no longer associated with "makos."

It's a nice meg for display and I very much like the stand.

Typo there either the “being”, but Carcharodon hastilis And Carcharodon carcharias are closely related to makos and I tend to call them such instead of great whites (when referring to them as a group) because if you call C. hastilis a great white it gets confusing (this is just my preference, I totally accept and support hastilis’s placement in Carcharodon)

Because C. hastalis is a white shark not a Carcharodon carcharias - Great white shark

In some places, great whites are simply called white sharks. If it would make people happy I’ll call them white sharks.  

But I also think that Megalodon is related to Isurus as well, I’m not sure which would be closer, probably the more basal Isurus.

"White" is a family name "great" is a common species name. Hastalis is a "broad tooth" white shark,  carcharias  is a "great" white shark. It is not improper to refer to either as a WHITE shark. It is wrong to call either a "mako" by current standards.

I have heard of nothing (other than Your opinion) that relates mako sharks or white sharks with megalodon sharks.

Do You have any references to support Your thesis?

I thought I read somewhere they both had a common ancestor, possibly isurolamna inflata. Although sometimes my mind does play tricks on itself sometimes.

Ok then, what would you guys put on an engraved name plate to be attached to Megs stand ? I cannot find the original reference to it being Otodus Megalodon, have scoured the internet to no availe, everywhere seems to still be using the Carcharocles Megalodon name still.

I’d put Otodus Megalodon but these things are transient and change with new evidence. @doushantuo do you have the reference? I remember the name Cappetta.

Here’s one paper (or part of it). Basically says in order for Otodus to be a Clade, Megalodon must be part of it (I think).

Thankyou for that, I just dont want to have a name plate engraved only for them to change the name yet again a few months down the line

Yeah a friend made it at christmas out of oak, it wasnt too expensive, he made a huge plinth for another friends icthyosaur backbone, here's his website, https://www.njcrafts.co.uk/

I am going to get him to make a new stand to display my Mosasaur tooth with a nice model of a Mosasaur I bought this week, will put it on here when its done.
