Hi everyone. I've come across this hadrosaur egg on a well known fossil/gem dealer's site. It's described as from the "Xixia Basin, in the Henan province of China", which research tells me has an embargo on hadrosaur eggs. It's a very well known gem/fossil site selling it, and states "This fossil specimen will come with a certificate of authenticity." (Authenticated by who exactly? Sure...) Naturally these pictures are as good as the resolution gets, and the price point (over $1k USD) seems pretty high risk for a possible fake. I've stayed away from eggs in the past since they're so rampantly faked, but eventually want one (from any dino, really) for my collection. Thoughts? Thanks!

Maastricht Natural History Museum Mosasaur central This charming little museum in a historic city is absolutely worth a visit if you have any interest in the latest Cretaceous and Mosasaurs. The city of Maastricht was founded by the ancient Romans along the Meuse (Mosa in Latin, Maas in Dutch) river. The animals we know as Mosasaurs are named after this river. The great lizard of the Meuse. Near the city are deposits of the latest Cretaceous, the Maastrichtian, which is named after the city. There are several quarries that produce a lot of fossils. In the same procince to the north of Maastricht there is another fossil location that lends it's name to a geologic age. The tiglien, which is during the lower Pleistocene, named after Tegelen. Part of the old roman city wall nearby. This museum also used to house the holotype of the original Mosasaur. Mosasaurus hoffmanni. Sadly it was taken as the spoils of war by Napoleon's army. Today the holotype is located in the Paris Museum of Natural History. So now there is only a cast of the holotype in the museum. This small glass enclosed area in the garden houses the holotype of Prognathodon saturator which is nicknamed Bér. The specimen consists of an mostly complete skull and a partial skeleton and was found near Maastricht. There are a number of articulated thoracic vertebrae, some limb elements and some other loose elements. Along with the mosasaur skeleton there were a lot of shark teeth (Squalicorax and others) found associated with it that suggests that the carcass was scavenged by sharks and other opportunists before being covered. I suggest viewing this on a cloudy day because the reflections on the glass can sometimes make it hard to see as well. Though the main attractions are the Cretaceous and Pleistocene fossils. There are also a few other cool things. An early relative of the Horseshoe Crab. A primitive spider.

Historic Dinosaur Vertebra Newly Recovered
Tennessees Pride posted a topic in General Fossil Discussion
I'm extremely excited to announce that two days ago at 3:30 a newly discovered dinosaur vertebra was recovered from a Late Cretaceous Campanian formation in West Tennessee. This is only the 4th. dinosaurian vertebra to ever be found in Tennessee! It's also the first dinosaur vertebra I've ever found in my life. The specimen is from the tail section on the vertebrae column of a Hadrosaur. The neural canal and neural arch are still plainly visible. Specimen is missing the neural spine and also possible Chevron bone. This is a historic achievement for paleontology in Tennessee and here is the first look. As I'm sure by now, everyone on the Forum knows, my cell takes terrible pics, I hope to prep the specimen soon and show better shots of it. These photos were taken the day it was recovered and I have no others presently available. I will post more pics on this thread when the specimen is cleaned.- 27 replies

2015 afforded to the opportunity to add some very nice new Cretaceous items to my collection from here in North Carolina. North Carolina offers several different formations of Cretaceous goodies. The Black Creek Group includes the Tarheel, Bladen and Donoho Creek Formations, all Campanian. Then of course there is the PeeDee, deposited during the Maastrichtian. This post will be photo heavy so it will take several posts from me to get everything in. First some of the Echinoids. These two Hardounia mortonis came from a sand pit in Pender County and are from the PeeDee Formation. Note that there are spines on both sides of these. Many of the echinoids from this location are exceptionally preserved. Next are Schizaster variabilis. These are the first 3 of this species that I have found, so they were welcome additions, also from the PeeDee Formation. One of these came from a location on the North East Cape Fear river, the others from the Brunswick River.

New hadrosaurid from Deep South
DD1991 posted a topic in Partners in Paleontology - Member Contributions to Science
A new paper regarding a new hadrosaurid from the eastern US is available online: Albert Prieto-Marquez, Gregory M. Erickson and Jun A. Ebersole (2016). "A primitive hadrosaurid from southeastern North America and the origin and early evolution of ‘duck-billed’ dinosaurs". Journal of Vertebrate Paleontology. Online edition: e1054495. doi:10.1080/02724634.2015.1054495. It's no surprise that we have been deciphering the evolution of hadrosauroids and hadrosaurids in North America during the late Turonian to Santonian interval, but the discovery of Eotrachodon provides new insights into the early evolution of hadrosaurids in North America by showing that hadrosaurids co-existed with non-hadrosaurid hadrosauroids in North America during the Santonian. However, the statement by Prieto-Marquez et al. regarding the geographical origin of Hadrosauridae should be taken with a grain of salt because Sebastian Dalman informed me of a soon-to-be-published tyrannosaur species from the Cenomanian of New Jersey and it's possible that a small number of Cenomanian-Turonian species from Asia currently classified as Hadrosauroidea incertae sedis could end up as basal hadrosaurids, in which case it may be clear that hadrosaurids in Laramidia made it to Appalachia during the Cenomanian before the Western Interior Seaway cut off Appalachia from Laramidia.- 20 replies

Hello again, I've posted this fossil before on here a couple weeks back, but I did some more uncovering of the fossil and made a few additions from rock fragments I found surrounding the fossil, so it is more complete now. It is from the fox hills formation in South Dakota, with the depositional environment being lagoonal. Professional papers collecting samples from this formation list shark teeth, mosasaur teeth, bivalves, as well as dinosaur bone fragments being found here. I think we can safely rule out bivalves though haha. The brown end of the fossil looks to be a jointed end of the bone. The black "fracture" above my thumb in the first pic looks like a bone suture, something that occurs only in skulls of vertebrates. I'm no expert on sutures but this "crack" looks like it didn't occur after death of the animal. I haven't had this theory confirmed though. Thanks again!

Hello, I found a fossil in the fox hills formation (Upper Cretaceous) around 6 miles east of Timber Lake, SD. I believe it is part of a dinosaur bone, or atleast a large vertebrate and was wondering if there was enough of the sample for a positive ID. The area in which I found it in is known to be a lagoonal deposition environment and I found the fossil in a thick bed of bivalves. Mosasaurs have been found in the formation but I'm not sure that this bone belongs to one of those. I tried to mostly clean it off, but there is still some encrustation.

Hey guys, Here's another weird hadrosaur egg from the same chain of dealers on eBay who's authenticity I questioned previously.. Never seen a white one before! What do you think? Kind regards, Lauren

A mysterious dinosaur egg from the late Cretaceous of China. Supposedly a small hadrosaurid, but still lacking a proper ID. -
Hey guys! This is a picture I drew of a fossil hadrosaur in its egg. I used pen to draw and Photoshop to give it some color. If anyone ever needs a paleontology illustration I'd probably do it for fun. Cheers! Lauren

Hey everyone. I went to Ramanessin brook today and found this. It is definitely bone and I believe it is a piece of a hadrosaur jaw. I'd love to know what you all think. Thank you!

Hey guys! If you have bids on hadrosaur eggs currently being sold on our favorite auction site STRONGLY RECONSIDER your purchase... There are several of them being auctioned right now from two different sellers. I bought one and received it on Monday. I was pretty suspicious from the get go, but my curiosity got the better of me. It came from Malaysia (red flag), was packaged well, and came quickly. It looked nice, but a little sketchy. Texture wasn't great. Already I decided I wanted to return it...but I also needed to know if it was really a hoax. That's when I decided to take a knife and scrape away the matrix from the egg for a few hours (I don't have any prep tools). Eventually my knife plunged through a hole. Within the hole I could see there was a small space between the base of the egg and matrix. At this point I decided, what the heck, and grabbed a nail and a hammer. I hammered away until eventually the matrix came off in chunks. One chunk came away with a piece of egg shell. Under the egg shell there were large amounts of glue. It was quite obvious at this point that this was just a piece of junk... With that said, don't make my mistake. I'm sure most people on here are wiser than I am, but the eggs looked reasonable, and the guy offered a full return. Maybe if I hadn't hammered at it I could have gotten my money back, but I had to know. At least I may save other people from getting scammed . Kind regards, Lauren

I recently purchased 2 Hadrosaur eggs, they were once joined but the matrix joining them has split (they can still be positioned as they were together, just with a visible crack where the split is). As they are heavy, fragile, and already split I want to display them and keep them safe, here's what I'm thinking: I have a plexiglas tray (thick) that they fit in nicely. I want to create a ground-cover like base that they can sit in, which will have some indentations to keep them from moving, and wanted to make this look like sand or riverbank mud as they would be found in their original natural state. Essentially making a nest or backdrop of their natural surroundings. Then I would place a plex cover to keep dust out. Rather than just fill the tray with sand (which would be messy, likely not too accurate, and wouldn't keep them in place), I want to pour in a wet material that I can sculpt and will dry to a nice base. Any suggestions on what to use? I could use plaster but that will add weight to an already heavy display. Ideally the material could have integral color (redish brown like the muddy matrix these eggs are found in), and some sort of a silty-sandy texture. I'm curious as to what others have used, done, or could suggest for my project. Thanks!

Why Do Hadrosaur Eggs Come In So Many Shapes And Colors?
-Andy- posted a topic in Questions & Answers
I am in the market looking for a Hadrosaur egg, and i am quite bewildered by the sheer number of variation in their shapes and colors. I am aware that fossilization and prepping methods differs, but I honestly wasn't expecting such a wide spectrum of different Hadrosaur egg types. So perfect it actually looks like it might hatch anytime Round, firm and cracked Flattened just like an Oviraptor's Bowling-ball type!

Here is my recent display change. I was going for a "museum" look. Unfortunately with this display, I can only show the main pieces until I figure out a way to display everything else and have it all still match with what I have set up now. Until then, they are tucked away in their cabinets!
