Baby Mosasaur
SPrice replied to snolly50's topic in Is It Real? How to Recognize Fossil Fabrications
Obvious clue it isn't real...the teeth should be 'baby teeth' instead of adult teeth. Not gonna fool anyone with that cuss word mistake! And talk about robust...this critter is so heavy it would be slithering through the seabed mud, imo. -
The seller describes this as Rare Natural Untreated Madagascar specimen. Sure looks unpolished to me.

Lower Carboniferous fossils of Ireland
Images added to a gallery album owned by Brian James Maguire in Carboniferous
All fossils have been collected and prepared by myself from the east coast of ireland. Carboniferous limestone makes up a good portion of the Malahide formation which yields good specimens of different species of Brachiopods, Bryozoans, both solitary and colonial Corals, Gastropods, Bivalves, Goniatites, both coiled and orthoconic Nautiloids, Crinoids, and if your lucky, Trilobites!- 9 comments

Anomotodon started following Mazon Creek trips

Just got back today from my first trip to Mazonia-Braidwood (pit 11) this year! I unfortunately couldn't make it on the opening weekend, and was afraid we won’t find anything this late - but I ended up being pleasantly surprised. By this point I ran out of concretions to freeze-thaw from last year, so I’m very excited for the next few months We decided to go back to the Tipple hill area. Here is what it looks like now - open, barren fields of rocks 99.9999% of which are not what we are looking for. What I found especially challenging about this area, is that there are numerous concretions that have perfect shapes, but are not actually the right type of rock - yellow/light orange. I haven’t seen them at other places within Mazonia. I tried cracking a few last year, but they just have quartz (?) crystals on the inside. I guess they are not actually from Francis Creek shale? I forgot to take pictures, but would be curious to hear from people familiar with this. And of course, here are a few dinosaur eggs (the right type of rock) in situ Here is the total haul. Probably not a lot for this site, but this is definitely the most productive pit 11 trip I’ve had so far. Even better, unlike my previous visits, this time I found quite a few fossils in already open concretions. Here is a shrimp molt Both halves of a Calamites I think this is a Cyperites leaf These two halves of Annularia whorls cracked on the drive home And, of course, a neat anemone - Essexella ascherae. Surprisingly, this is the only one we found (so far). Will keep this thread updated with new fossils as I freeze-thaw the remaining concretions. I will also be back to Mazonia this weekend, but will probably go to a different site. I’m hoping this will become a mega-thread of all of my future Mazon creek trips. Out of all of the fossil sites I ever collected at, this is genuinely one of my favorites, if not the favorite - amazing fossils you can’t find anywhere else, plus instant gratification from finding concretions is always followed by delayed gratification over months of opening them. Here are my past trips to Mazonia and Braceville in 2023:

Looks great! Much nicer to look at, and close enough to the original color to look good, but different enough to show what is original and what is restored

Baby Mosasaur
Doctor Mud replied to snolly50's topic in Is It Real? How to Recognize Fossil Fabrications
Got me thinking from what is a baby Mosasaur called….thought should be what we call its closest living relative. Snakes and monitor lizards - hatchling. But did mosasaurs lay eggs? https://eartharchives.org/articles/a-new-beginning-for-baby-mosasaurs/index.html# A tangent but - that’s how my brain works sometimes! Especially after coffee -

Finished! I'll start with saying of all the arts I'm bad at painting so going into it I really just wanted to highlight the texture, that being said I still think it turned out good. all in all I'm fairly pleased with how it turned out it is obviously restored but I think it helped a lot from the base clay. All in all it was a great learning experience thanks for tagging along!

Baby Mosasaur
Doctor Mud replied to snolly50's topic in Is It Real? How to Recognize Fossil Fabrications
It must be all good it’s sitting on a field jacket. And the Mosasaur younglings had no need for ribs or flippers, better defense . Just solid vertebra all the way! What do you call a baby Mosasaur? E.g. a baby cow we call a calf. I guess this one is a mess-osaur overall -
Nice find! We can be spoilt by seeing the multitude of Mosasaur teeth coming from other places in world - but in some places they are a rare treat.

Unpolished Ammonites from Madagascar
Wrangellian replied to Alvrr.0's topic in General Fossil Discussion
This is most of my Madagascar ammos (the pearly ones and the Perisphinctes). I forgot that a few of them have squared-off apertures but otherwise all natural. The Perisphinctes in the upper left has a squared aperture but the ribbing thankfully has been left intact. I forgot to mention I also have a nice Douvilleiceras from Madag. that is basically unaltered except for a clumsy partial prep job.- 10 replies

Very nice, thanks for sharing! Glad you are making the best out of this spring. I must point out, however, that the tooth is a mosasaur tooth, not necessarily a Mosasaurus genus tooth. Unless, of course, you are certain that it is of that genus, in that case don't mind me!

I see lots of crystals that look like pyrite all over the thing. If it's heavy it could be mostly pyrite.

9 might be a Cretodus tooth, 10 and ll looks like Cretolamna Appendiculata. Nice finds.

I just returned from a few days up in NJ where I had time to visit Big Brook (and Ramanessin for a little bit too). I went for a couple hours last Wednesday when I first arrived, then picked up where I left off Thursday morning. It was pretty chilly. About 28 degrees when I first woke up at 7. So I did some other work at the Colt's Neck Inn Hotel (highly recommend) until about 11. Over that time it warmed up almost 10 degrees. But I headed out. The positive to the cold weather was that I was the only one out there. It was also sunny despite the cold, and was otherwise a great day to go out. About 2pm and nearly to the Boundary Rd bridge, sifting through pile after pile of gravel, this beauty rolled across my sifting pan and I could hardly believe it. After a good 5 years and several trips, I finally found my first mosasaurus tooth! It's a bit beaten up and chipped, but I couldn't have been happier. Totally worth my beet red hands. This was my big trip maker and will have an honored place in my special fossil cabinet.

Wow! What erudite analysis of the specimen. I had hoped it was a merychipine since I don't have any of those in my small collection. I was amazed to find it on online auction site and even more amazed that no one else bid on it. A deep bow to you and thank you very much for your informed opinion.
