Big Brook Fossil ID


Marco L

Recommended Posts

Hello again, I have two more specimens that I cannot ID. I suspect the long yellowish rod is a belemnite, but it looks odd. It has a hole on hole side, but no hole on the second side. The small tooth like object is small and is not hollow, could it be a Saber toothed salmon tooth?

 

Thanks,

Marco

I agree with the 2nd specimen being "Saber toothed salmon" or Enchodus for short ;)

 

Not sure about the first guy.

Second that. Looks like it to me.

 That is from the phragmocone.

I always thought the common-name was "saber-toothed herring", not "salmon" :P

I think they are more closely related to salmon.

Enchodus was related to lancetfish and lizardfish.  The terms "saber-toothed herring" and "saber-toothed salmon" are colloquialisms invented by collectors based on superficial resemblances; Enchodus was not closely related to either herring or salmon.  Much like the "Ginsu shark" (Cretoxyrhina), which is not actually related to Ginsu knives.

Yes I usually hear “herring” more often, but I believe I’ve also come across “salmon” before. I had also heard they were closer related to salmon, but maybe that is old info.

Wait! Wait! You mean to say Ginsu knives aren't actually made using Ginsu sharks? How else could they be made? :default_rofl:

Where'd you get this information from? My version of Wiki reiterates what Don wrote...

Here My version (vision) of Wiki is that I don't trust Wiki.

Well, in any case, Aulopiformes are likely a sister group to the Salmoniformes so still more closely related to the salmon than to the herring.
