Recommended Posts

Calvert Cliff Dweller

Hi Guys,

 

Thanks for the help on the Sturgeon ID last night folks. I have one more for you tonite, I acquired a supposed Possible early Cretaceous item from Prince George’s County Maryland. Anyway I could definitely use some help on this peculiar looking fossil. Thanks in advance folks I know somebody on the forum can nail this Alien looking creature down.

That looks like a nice chunk of jaw from the pycnodont fish Anomoeodus (or possibly some close relative).  Anomoeodus single teeth turn up pretty regularly in New Jersey and Maryland Cretaceous marine deposits, but it's a lot less common to find a bunch still in the jaw like this.

I'd say pycnodont as well.

Nice find. :)

Wow, that’s a great acquisition:envy: Cretaceous stuff from Maryland is super rare, mostly because it’s hard to gain access to productive Cretaceous sites in Maryland.

I know access is very hard  to find up there. I appreciate the help guys IDing this Cretaceous fish material. I spend most my time playing in the young Miocene down here in Calvert. Here are a few examples of Calvert formation fishes. Sturgeon dermal scutes  and I let one of you knowledgeable fisherman tell me the right punctuation for the Stoney growths shown in the photo.

The Anomoeodus mouth plate is probably Upper Cretaceous. I believe all of the marine Cretaceous formations in Maryland are Upper Cretaceous. It is a spectacular piece! Congratulations. Your other Miocene fish material is pretty cool as well. Thanks for sharing it.

Maryland used to be a magnificent source of great Cretaceous marine fossils; ammonites, gastropods, bivalves, and vertebrates. Sadly, almost all of the sites were destroyed by development. Here is a sample from the Monmouth Amateur Paleontological Society collection:

Yeah, I know. Sometimes I’ll look at the old journals that speak of and show plates of finds like these from Maryland and just marvel at how great they are and at how quickly the sites were erased from the face of the earth. Google earth reveals parking lots and malls were once were ammonites and mosasaur teeth. Saddens me that I missed those days, and motivates me to collect where I can while I can.

Those are some fish hypural bones. By the way, the Anomoeodus plate is very nice.

Most of those look like some type of fish jaw sections.

I believe the smaller jaws are maybe Drum fish and the two larger jaws are wahoo.

It did not really resemble some of my other ray material. But now that you mention it I can see that.
