The Spring 2017 Gem and Mineral Show was very successful. The parking lot was filled to capacity and we made over $3000 for the scholarship fund. I think it helped that it was so cold on Saturday, because people wanted to do something indoors. Here are some of the highlights.

INVITATIONAL EXHIBITS (more…)
Paleontologists at the University of Toronto just found collagen in a 195 million year old fossil. This makes it the oldest protein that has ever been found. Previously, the oldest protein sample was only 80 million years old (it was also collagen, from a dinosaur bone). They also found hematite crystals in the fossil, which possibly came from the blood. The dinosaur was a Lufengosaurus that lived in Yunnan Province, China.
Some other paleontologists didn’t like the new, non-invasive methods that the team used used to identify the collagen, but other scientists thought the methods were fine. Read the whole article here https://cen.acs.org/articles/95/i6/Collagen-found-195-million-year.html and let me know what you think.
When: 6:30-8:30 p.m. Friday, June 17 (21 and older)
Enjoy drinks and light bites while you view a fascinating collection of fossils and hear from renowned University of Kansas Paleontologist Dr. David Burnham about the unique and ferocious Dakotaraptor. Prepaid reservations of $30/person or $25/member required. You can make those reservations at https://www.powellgardens.org/dino-soiree or by calling 816-697-2600 x209.
Guests will get one drink ticket, which can be exchanged for wine, beer or a non-alcoholic beverage at the bar. Additional drinks will be available for purchase.
Come early if you would like to take a self-guided tour of Jurassic Garden: A Prehistoric Adventure! If you cannot make the paleontology lecture, there are some other events at the Jurassic Garden: Dining with the Dinos on June 24 (reservations for BBQ dinner with dinos) and Dino Night July 22 (reservations for Dino Night). The Jurassic Garden will be available until August 14, 2016.
I took way too many photos at the show and most of them were interesting, making it difficult to write this post. Without further ado, here are the highlights from the Spring 2016 Gem and Mineral Show.
In this article from Chemical & Engineering News, researchers use chemistry to find out what colors the dinosaurs were.
Researchers led by Johan Lindgren of Lund University, in Sweden, used a battery of analytical techniques to scrutinize the molecular makeup of a fossilized Anchiornis huxleyi specimen. This dinosaur is a distant relative of today’s birds, and its remnants were preserved for about 150 million years in what is now northeastern China.
The researchers’ thorough analyses have allowed them to conclude that some of the dinosaur’s melanin, or pigment molecules, and melanin-producing organelles have also survived the intervening epochs (Sci. Rep. 2015, DOI: 10.1038/srep13520).
Scientists have previously observed signs of similar biomaterials in fossils, but studies have lacked sufficient evidence to rule out the idea that these materials come from bacteria or other microbial intruders.
Using methods including infrared spectroscopy and time-of-flight secondary ion mass spectrometry, Lindgren and his colleagues have shown that the sample’s fossilized feathers contain substances that closely resemble modern animal—not bacterial—eumelanin, the pigments responsible for brown and black coloration.

Hypsibema missouriense is a type of dinosaur called a Hadrosaur or “duck-billed” dinosaur. It was a herbivore with jaws that contained over 1,000 teeth. Hypsibema had evolved specialized teeth to handle the tough, fibrous vegetation of the time. This dinosaur lived in Missouri during the Late Cretaceous Period. Hypsibema was first discovered in 1942 by Dan Stewart, near the town of Glen Allen, MO, and became the state’s official dinosaur on July 9, 2004 (RsMo 10.095) A reconstruction of Missouri’s State Dinosaur can be seen at the Bollinger Museum of Natural History in Marble Hill, MO.
