#FossilFriday mosasaur news!
It's been a while, but happy to see my MPhil research out @ZoolJLinnSoc! Together w/ my coauthors we examine:
-1st M. lemonnieri (?) record from DK🇩🇰
-Rare BABY mosasaur teeth
-Geochem🧪 data for eco-diversity near the K/Pg

Everything IS bigger in Texas...
Introducing TYLOSAURUS REX–“TEX”. A monster animal, a monster paper, & a monster project that I am *so* excited to finally share with everyone after ~5 yrs. Huge thanks to my coauthors, Mike & Ron, & to Alderon Games for bringing our lad to life!!

Incredibly excited to be in #Maastricht for the 175th Anniversary of the Maastrichtian conference!! If you're curious about giant cephalopods 🦑, be sure to come to my talk in Centre Céramique tomorrow at 10:35 AM!

@TheLongestJohns The Mary Ellen Carter would make for a wonderful community video!

[Cephalopods Daily @CephalopodToday]

Cranchiidae has to be one of my favourite family of squids. Cranchiids are funky looking, many are transparent and they have a special chamber filled with ammonium to help them float.

@BobNichollsArt Very lovely to have the wonderful biota of the Danish Chalk depicted by you! Such a beautiful artwork, I always like seeing it every time I go to GeoCenter😊

[Christian Voiculescu-Holvad @Chalkologist]

@PrincessAiraB @GeolSoc Congratulations Princess, this is brilliant!! So so well-deserved 😊

Interested in Danish fossils? And/or helping build a fossil collecting community? Our new fossil website https://t.co/0SCF06lTju has just launched! 🥳🦖🎉

Upload your own (Danish) finds and help identify others!

Another new species, another exciting discovery tainted by the use of AI images...

Marambionectes is a new plesiosaur genus from Antarctica. Unfortunately, the describing authors resorted to using AI-generated images to promote their research. Not a good look.

Happy #MosasaurMonday! Featuring mosa-models from @PrincessAiraB and @raheem07183, a mug, the Oceans of Kansas book by Mike Everhart, and courtesy of @NHM_Denmark & Geomuseum Faxe... the majority of the Danish🇩🇰 mosasaur fossil record for me to study🥳

[Christian Voiculescu-Holvad @Chalkologist]

@BobNichollsArt Congrats, this is very well deserved 😁 All your palaeoart is of exceptional quality!

[Christian Voiculescu-Holvad @Chalkologist]

@PD_Mocho There's really been quite a bunch of mosasaur research being published lately, and I'm all here for it! That holotype skeleton is beautiful😁

[Christian Voiculescu-Holvad @Chalkologist]

@tomsharperocks A very historic moment in the development of vertebrate palaeontology. And that Plesiosaurus drawing Mary Anning made is very nice; she definitely had a talent in illustrating the specimens she collected. And she only kept improving (her Squaloraja sketch is even more detailed)!

[Christian Voiculescu-Holvad @Chalkologist]

@Paleoartologist Damn, congrats on graduating! Also studying those beautiful Maastrichtian type mosasaurs from Belgium? That's incredibly epic 😄

[Dr. Jasmina Wiemann @jasmina_wiemann]

Exciting new paper:

@MadisonTripp_ et al. show endogenous organic matter preserved in #fossil plants from Mazon Creek, incl. diagnostic arborane and fernane compounds. 🌿

➡️Powerful new approach for resolving plant parataxonomy!

@ThePalAss @kunhm Oh this is lovely, I'm very glad Part M Decabrachia is now open access 🥳

[Christian Voiculescu-Holvad @Chalkologist]

@Gamarraptor This is absolutely beautiful, such a nicely done piece 😁 We need more Late Cretaceous "giant squid" to feature in palaeoart!

Ragnarok has arrived - happy #MosasaurMonday!
It is my pleasure to introduce JORMUNGANDR WALHALLAENSIS, a new mosasaur from North Dakota! I’ve worked on Jorgie with Clint & Nathan for the past ~1.5 yrs & I am BEYOND stoked to finally share it with everyone!
