Vinctifer (Gar) species ID verification Request

[Ruger9a]

Good morning folks.  I have what I believe is Vinctifer (Gar) species fossil fish.  It was listed only as "Fossil fish, Brazil" and was located in Brazil.  My research reflects it's from the Cretaceous, Santana Formation, Brazil.  The fish appears to be "belly up".  I carefully removed some matrix to see if the hidden portion was sill there, but gave up as the matrix is too hard.  It will be glued back.  Am I off base with the ID?  Help please.

This is Rhacolepis buccalis. 

 

Vinctifer comptoni has scales like this:

@oilshale  & @gigantoraptor Thank you guys!  Finally I can put an ID card on it after 18 years of collecting dust.  

I have four split concretions with fish, three are from Atlas Mountains, Morocco and one from "Argentina or Brazil" (seller didn't remember which).  Are you feeling in a generous mood today?  Would you care to take a stab at seeing if they are identifiable?

Keep 'em coming

Also from Morocco

I understand the position of the first two fish may be a problem.

This is the one from "Argentina or Brazil"

Here's the last one from Morocco.

All of these fish are from the Triassic of Madagascar. 

 

Have a look through this topic. 

 

I think  1, 2, and 4 are Pteronisculus macropterus.  Very difficult to say for sure. 

I think 3 may be a Boreosomus. gillioti.

Yep, Madagascar.  Nice fish too!

@oilshale

Exact. Typical concretions...and fishes.

@oilshale

I would say Pteronisculus cicatrosus; P. macropterus has abnormally long pectoral fins. They almost reach up to the ventral fin. 

Not 100% sure with 3 either - but I think Tim is right: Boreosomus gillioti. The dorsal fin begins already in the front half of the body.

Thanks for the correction, Thomas.  

I am still iffy on the Madagascan fish. 

[Ruger9a]

All Madagascan fish and all with names, periods and locations!  Wow, what more could you ask for.  I'm so thankful we have such dedicated experts in this forum.  THANK YOU ALL!!  

Darn, I just looked at Thomas's link (above) and I noticed I had already printed it out for reference.  But, I foolishly disregarded it because it was for Madagascan fish.....
