Livvi's mammal jaw

Diggers may recall that Livvi found a mammal jaw on her first day back at the dig (Saturday 7th March).  Following Lesley's tradition of giving the most promising fossils easy to remember numbers, it is #200 in the Field Catalogue.  Diggers may also recall that Livvi and her friends looked for half an hour before locating the other half.  I can report that her mammal jaw does indeed have a tooth - just one, towards the back of the jaw.  The crown is in that "other half", and so delicate that Dave expects it will not be extracted and have to be scanned.  Cool.

The thing that Tim found...

Crew attending week 3 will know that Tim found something quite interesting on the last day at site (Friday 20th March).  He walked the stable half  (mainly imprint since the other half splintered) around to show the diggers.  It was way too big for one of our mammal jaws so I labelled it "possible ornithopod maxilla" in order not to get anyone's hopes up (but I did put it in the priority box for Dave to look at as soon as possible, and took photos to show Tom and Lesley in the meantime!).  I am now hearing reports from the lab that it is every bit as exciting as we hoped.  Possibly so exciting, in fact, that I'm not a liberty to give away too much.  It will get micro-scanned soon, and hopefully give up some more of its secrets.

Dinosaurs Dig Paleontologists Who Do Math

A paper written by Tom Rich et al using statistical analyses to confirm that Serendipaceratops arthurcclarkei is a ceratopsian was recently celebrated in Math Horizons, an American high school and university mathematics magazine.
Some of you know that my first (academic) love was mathematics, so it's great to see a math journal talking about our dinos.

Check it out at Math Horizons.
