Who wouldn't love to be this kid?
The 9-inch Iguanodon footprints he found are amazingly clear and well-preserved - you can check them out at the Daily Mail's story online, along with a cute pic of Rhys smiling and pointing to his clever find. Experts say that based on the size of the footprints, Rhys and his dinosaur are roughly the same size.
The story goes on to say:
"His only disappointment is that they are prints from a plant-eating dinosaur. He would rather they had been from one of the big meat-eating ones like a Tyrannosaurus Rex because they are his favourite."
With all of the extremely bright kids that come to our Museum and dream of finding dinosaurs, it is extremely cool to see one who's done it. Congratulations, Rhys - you may just have a new favorite.

Dr. Bakker's new book: Prehistoric Monsters!
Dr. Bakker's latest book is out - and it's for kids! Well, I enjoyed it qute a bit, too - so maybe we should say it's for kids, and that kid inside all of us that still geeks out over 12-foot sea scorpions and the idea of Quetzalcoatlus zooming by overhead.
Speaking of geeking out - Dr. Bakker also talks about our Seymour dig program on the page that covers the Permian, right next to a Dimetrodon attacking and Edaphosaurus - both of which we've found evidence of at our sites. Woot!

VIDEO: Nicole in 3D - CT scans of our favorite lysorophus
The cloudy red area you see in this video is the rock surrounding the fossil itself. The more defined, lighter sections show the fossil itself. As the image rotate, you can see the ribs and spine curling around. In life, it would have looked something like a pile of coiled rope, with each coil resting on the one under it. Stretched out, Nicole would have been about 18 - 20 inches long.

Note to Eocene: You can fossilize, but you can't hide
Some days, he's got volunteers working on the sediments brought back from the Museum's dig site in Seymour. Recently, he's introduced a table full of Eocene-era sediments from the area around College Station, TX.
In this video, David explains this particular project, where these fossils came from, how they ended up preserved so closely together, and how our volunteers are analyzing them.
Todd is a patient, very thorough fossil hunter - here, he identifies several Eocene fossils for us, shows us how to use his tools, and lets us in on why he wants to be a paleontologist - despite David's vivid descriptions of what a hard, tedious job it can be sometimes.

David Temple - Lysorophus found!
The perils of marriage to a paleontologist
I first met “Nicole” in a wash about 800 meters from the main quarry our team has been working in Seymour. The day was winding down, sun was shining at a raking angle, and we were all tired of sitting on lumpy, pointy rocks.
So, we took a short paleo “road trip” and in order to do some prospecting. The Doctor and Flis headed south and east, I went north and west.
Usually, this kind of contrarian behavior on my part results in the opportunity to admire everyone else’s fantastic finds. You would think that since this happens so often, it would encourage me to follow the pack. Still, it’s at least a little easier on the ego to admire everyone’s discoveries back at the vehicles, rather than at the outcrop. (Particularly after they have asked me to move some part of my body so they can retrieve or examine said fantastic find, which I have been unwittingly laying or sitting on. I have not been successful in arguing that standing, sitting, leaning, lying, on or next to a fossil, constitutes “discovery.”)
When I brought “Nicole” back to the vehicles to meet the folks, as it were, I knew the kidney-shaped rock was something interesting, as The Doctor immediately became very excited. It was a Lysorophus, a small amphibian that resembles a modern amphiuma. Faint outlines of ribs could be observed sinuously disappearing into the rock.
This was the fossil of a complete animal, still coiled in its burrow. During the late Permian it had burrowed in the mud to escape drought and wait for rains that never came.
The fossilized Nicole. You can see the ribs curling around the lower right corner.
In his excitement, the doctor called for a name. As is his habit, he suggested the name of my first girlfriend. This required some thought, as I briefly but awkwardly recalled her identity, realizing that the minimal qualification for “girlfriend” status is mutual affection.
Then – thankfully – I experienced a moment of clarity, a fast mental flash-forward, as I return home to the missus with news of the find, the name and an explanation.
“But Sweetheart, I could never name a wriggling, tiny-limbed, slime-covered amphibian that burrowed in the mud and ate by sucking - and a dead one at that – after you! I’m saving that honor for the discovery of a graceful, long-limbed and beautiful new species.”
A Lysorophus closes in on its prey. (c) Robert T. Bakker
“Does anyone know where the love of God goes;
When the words turn the minutes to hours...”
No matter what you’ve found, naming opportunities are few and far between. So, I did the smart thing and named it after the wife, who was polite but not particularly enthusiastic, despite assurances that I had no hidden agenda in naming a dead, wriggling, tiny-limbed, slime-covered, mud-burrowing, suck-eating amphibian specimen after her – that this act was, in fact, complimentary.
Defending this claim was problematic. So, I reminded her that 292 million years ago, this thing was quite a looker…. at least to members of its species… maybe even the cutest one…and after all, it was very thin.
Hello Rock, meet Hard Place. If I ever get christening rights again, I am sticking with U.S. presidents, beloved pets or Batman villains.
I think I made the correct choice – would you have done it differently?
Nicole – the fossil, not the wife – will eventually end up freed from her burrow and on display in our new paleontology hall.
