Fantastic fish fossils

I got some of similar origin last year - I have them as my avatar

If it doesn't delay any longer, next week I will receive another polished piece from Madagascar, "I liked it too", and another trilo for the collection.

MrsR gave me my only polished ammonite in my collection a Cleoniceras from Madagascar . I keep an eye out for your new bug.

So last weekend I had an incredible time first time fossil hunting in Isle of Wight with @Haravex

 

Thanks alot for being so kind and awesome and showing me the ways and teaching me where to look and what to look out for, what is needed to extract, things to be aware of etc!

 

Here are some of my fossils finds. The highlight find was an Iguanodont spitter tooth (Second pic)! Also found three really nice Lepidotes sp. fish teeth (See 3rd pic left), Gastrolith, fish scales, a limpet shell and saw alot of bone material and other cool things! 

 

Lepidotes is an extinct genus of Mesozoic ray-finned fish which have been found in Jurassic and Cretaceous rocks worldwide. Inhabiting both freshwater lakes and shallow seas, Lepidotes was typically about 12 in long. The body was covered with thick, enamelled scales. Batteries of peg-like teeth enabled Lepidotes to crush the shells of its molluscan prey. Fossil examples of these teeth were collected in medieval times as 'toadstones', claimed to be found within the heads of toads and to have magical powers against poisoning. (See 3rd pic showing the three that I found and a section full of teeth on top right from a publication belonging to Lepidotes maximus).

 

I came across a largish piece of fractured Gastrolith embedded in the matrix which had to be extracted. I think I'll try to piece this back together soon as there aren't too many pieces from what was salvaged.

 

Finally also got to see some dinosaur footprints on my walk along the coast from Compton Bay to Brook Bay to Brighstone Bay. Also got to visit sights such as the Needles (a row of three stacks of chalk that rise about 30m out of the sea).

 

I hope to go back to IOW again soon but when it's raining as I am curious as to what the weather could expose as last weekend was really sunny!

Received a really exciting fossil today. Not only because it is an amazing organism I've wanted for a long time but also because it is something I never expected to arrive.

 

I purchased this fossil fish the day before the military conflict in Ukraine began, and as a result completely forgot about it. But the seller ended up reaching out to me and told me that amazingly it was able to be sent out and made it out of the country. Today it arrived, probably even quicker than the last time that I had purchased a fossil from this same seller.

 

The main piece is a Zascinaspis heensi which seems very complete and preserved in great detail. You can see the dorsal shield, location where the fin would have attached, the rostrum, eye, and many of the details of the surface of these bones is preserved as well. Alongside it is the ventral shield which the seller labeled as Podolaspis letichei, almost completely exposed and also preserved quite well.PXL_20220325_173048667.thumb.jpg.ff3e9f13558cb0232c9b1a9841cdacc2.jpgPXL_20220325_173107627.thumb.jpg.a58eca4b8cf5dfddebaf1e21a55db6c6.jpg

additionally the seller also included as a little extra this partial skull roof from Kujdanowiaspis sp. from the same region. It is a partial but I still quite like it as it is also a very interesting fish and this one is a bit larger than my other Actinolepid skull from this location.

PXL_20220325_173126855.thumb.jpg.29b5b7bdfd18ff90ed4cc5ebd66574ea.jpgPXL_20220325_173119211.thumb.jpg.9d36b793474ef199571ba4baf9a693d8.jpg

all of these are lower Devonian (Lockhovian) from the Dniester formation in the Ternopil oblast of Ukraine.

Those are some very lovely specimens!

Nice! I think it is a very special fossil. Every fossil is special, even if it was not super expensive. :) I think it is a very beautiful specimen.

Great looking stands (and fossils). My opinion: If I had those I wouldn't use stain. If it came out fairly dark the fossils would hide / blend in too much I think. I would probably go with a polyurethane or a spar finish. Will still darken the wood a bit but allow the fossils to stand out. Again, just my thoughts. Though, yes, some stains can be pretty light (some oaks come to mind). I guess I always think darker stains, walnut, cherry and the like.

I agree @fossilhunter21that darkening them would make the exposed pieces stand out less.
In my opinion I would not give them color, just clear varnish, they are very beautiful in their natural state.

Beautiful stands, really good work. I also would stain them a little darker  I think that would knock them back a bit and draw the focus more to your cool fossil . Just my opinion. Cheers Bobby

Wow what a collection! May I ask why you collect so many teeth it seems from the same species?

Well, I only collect the truly big ones now... alot of the smaller ones I personally dug up on 4 separate dig field trips while in Morocco...

Here are some of the fossils that came in for me over the past one-and-a-half week or so.

 

First up is the cervical vertebra of a Platecarpus coryphaeus mosasaur from the Smoky Hill Member of the Niobrara Formation of Gove County, Kansas. Interestingly, it turns out this is the same specimen I missed out on buying just under a year ago, so I'm very happy to have gotten it now: it's preservation is just wonderful, and it's hard to find specimens of this quality this side of the Atlantic...

 

507917473_Platecarpuscoryphaeuscervicalvertebra02.thumb.jpg.f6d0d645e61e8dcbe44c10598efaad19.jpg426923957_Platecarpuscoryphaeuscervicalvertebra03.jpg.b451a16715145f228efcdfbb39f6aa93.jpg13986338_Platecarpuscoryphaeuscervicalvertebra04.thumb.jpg.a3412dccf0fcd13abd476e505ec4bfa5.jpg646994101_Platecarpuscoryphaeuscervicalvertebra01.jpg.31813e1125dc159093a5b8db77bb3e35.jpg

 

 

The second specimen is a great plesiosaur vertebra from the Akrabou Formation at Asfla in Morocco. While I've got a couple of pliosaur/polycotylid vertebrae from this location, this is my first elasmosaurian - Libonectes atlasense - from the locality, a cervical from an adult individual with (partially) preserved spinous process, no less (due to how fragile they are, the spinous process typically breaks off)! It also has a beautiful keel.

The pieces I'm probably most stoked about, though, are these two plesiosaur teeth from the Kem Kem Group. A couple of them have shown up on the forum before (here and here), but with how rare these are (albeit possible due to frequent misidentification), I've had to wait a long time to get them. The teeth have fine striations lingually, with some extending distally. However, neither tooth apex nor labial side bear any ornamentation. The teeth are elliptical in cross-section - with one taking on an almost triangular shape, reminiscent of the plesiosaur tooth from the Cenomanian deposits at Boujdour shown here - and both are mesially monocarinate (with the carina on the more conical tooth, however, only present apically). This carination gives the teeth a mildly subtrihedral cross-section, like a watered-down version of what is encountered in certain polycotylid teeth from the younger Akrabou Formation (near Goulmima), possibly foreshadowing what was to come, as both ornamentation and carination correspond well to teeth found at that locality.

To my knowledge it's still unknown from which formation in the Kem Kem Group these fossils derive. But based on the colour and coarseness of grain size still adhering to some of the specimens and following Ibrahim et al. (2020), it seems possible they derive from the Gara Sbaa Formation, and, thus, are early Cenomanian in age, from a time when aforesaid authors postulate the palaeoenvironment in the Kem Kem to have been deltaic rather than the low-energy coastal environment proposed for the younger Douira Formation. Such seems confirmed by the presence of a polycotylid plesiosaur in the assemblage of the likewise early Cenomanian Bahariya Formation in Egypt, which, however, represents an entirely different ecosystem - a lagoonal.

The second specimen is a great plesiosaur vertebra from the Akrabou Formation at Asfla in Morocco. While I've got a couple of pliosaur/polycotylid vertebrae from this location, this is my first elasmosaurian - Libonectes atlasense - from the locality, a cervical from an adult individual with (partially) preserved spinous process, no less (due to how fragile they are, the spinous process typically breaks off)! It also has a beautiful keel.

The pieces I'm probably most stoked about, though, are these two plesiosaur teeth from the Kem Kem Group. A couple of them have shown up on the forum before (here and here), but with how rare these are (albeit possible due to frequent misidentification), I've had to wait a long time to get them. The teeth have fine striations lingually, with some extending distally. However, neither tooth apex nor labial side bear any ornamentation. The teeth are elliptical in cross-section - with one taking on an almost triangular shape, reminiscent of the plesiosaur tooth from the Cenomanian deposits at Boujdour shown here - and both are mesially monocarinate (with the carina on the more conical tooth, however, only present apically). This carination gives the teeth a mildly subtrihedral cross-section, like a watered-down version of what is encountered in certain polycotylid teeth from the younger Akrabou Formation (near Goulmima), possibly foreshadowing what was to come, as both ornamentation and carination correspond well to teeth found at that locality.

To my knowledge it's still unknown from which formation in the Kem Kem Group these fossils derive. But based on the colour and coarseness of grain size still adhering to some of the specimens and following Ibrahim et al. (2020), it seems possible they derive from the Gara Sbaa Formation, and, thus, are early Cenomanian in age, from a time when aforesaid authors postulate the palaeoenvironment in the Kem Kem to have been deltaic rather than the low-energy coastal environment proposed for the younger Douira Formation. Such seems confirmed by the presence of a polycotylid plesiosaur in the assemblage of the likewise early Cenomanian Bahariya Formation in Egypt, which, however, represents an entirely different ecosystem - a lagoonal.

 

Nice fossils

 

Glad you managed to get some Kem Kem Plesiosaur teeth. Very cool.

Well, here is my last entry.
A Cleoniceras sp. polished 14 ctms. from the Lower Cretaceous of Mdagascar.
