The Denver Gem and Mineral Guild is proud to offer our junior members a special group called the GOLDEN DIGGERS. The program is to increase interest in rocks, minerals and lapidary arts. Junior members range from 4 years old to high school. We strive to make these meetings fun, educational and hands-on.

Parents are encouraged to join their kids and take part in the activities.

Our Golden Diggers program is led by Joseph Payne, who has been an active member of the Guild for over 20 years.

Meetings:

During the year (September-May) the GOLDEN DIGGERS meet for one hour at 6:30 pm prior to the regular DGMG meeting at the Colorado School of Mines Berthoud Hall room 109. We are using the American Federation of Mineral Societies Future Rock Hounds of America program to provide structure. (For more details go to www.amfed.org/kids.htm and www.amfed.org/kids_links.htm.)

Topics covered at the meetings may include:
Rock and mineral identification
Fossils
Lapidary arts
Gold panning and prospecting
Mineral and fossil collecting
And much, much more.

Field Trips:

Time to "Get off the mouse and out of the house!" During the months of June, July and August, the Golden Diggers go on family field trips for mineral, fossil or gold collecting. These field trips are sometimes to mines and private ranches that are NOT open to the public. Come join Denver Gem and Mineral Guild for only $25/year per family by clicking HERE.

Colorado State Fossil and Geologic Time Scale

 6 Facts About the Colorado State Fossil the Stegosaurus, by Bob Strauss Updated September 26, 2018

01.           Stegosaurus Is the State Dinosaur of Colorado 

1980 Students from the McElwain Elementary School in Thornton started a write in campaign and were joined by thousands of fourth-grade students to have the State recognize the Stegosaurus as the official Colorado State Fossil.  With the guidance and encouragement of their teacher, Ruth Sawdo, the children were successful.  On April 28,1982 the Governor of Colorado signed a bill making Stegosaurus the official state dinosaur, after three years of hard work. .

02.        Stegosaurus Had a Brain the Size of a Walnut

Given its size, stegosaurus was equipped with an unusually small brain, comparable to that of a modern golden retriever — which gave it an extremely low "encephalization quotient," or EQ. How could a four-ton dinosaur possibly survive and thrive with so little gray matter? Well, as a general rule, any given animal only has to be slightly smarter than the food it eats (in stegosaurus' case, primitive ferns and cycads) and just alert enough to avoid predators—and by those standards, Stegosaurus was brainy enough to prosper in the wilds of late Jurassic North America.

03.        Paleontologists Once Thought Stegosaurus Had a Brain in its Butt

Early naturalists had a hard time wrapping their minds around the diminutive size of stegosaurus' brain. It was once proposed (by no less an eminence than the famous American paleontologist O.C. Marsh) that this none-too-bright herbivore possessed supplementary grey matter located somewhere in its hip region, but this was dispelled when the fossil evidence proved unavailing. (To be fair, this theory wasn't as ridiculous then as it seems now when we know a lot more about dinosaur anatomy!)

04.           There's a Lot We Don't Know About Stegosaurus' Plates

The name stegosaurus means “roofed lizard” , reflecting the belief of 19th-century paleontologists that this dinosaur's plates lay flat along its back, like a form of armor. Various reconstructions have been offered up since then, the most convincing of which has the plates alternating in parallel rows, pointy ends up, from this dinosaur's neck all the way down to its butt.

05.       Stegosaurus Was One of the Earliest Dinosaurs to Evolve Cheeks Although it was undoubtedly lacking in other respects, stegosaurus did possess one relatively advanced anatomical feature: extrapolating from the shape and arrangement of its teeth, experts believe this plant-eater may have possessed primitive cheeks. Why were cheeks so important? Well, they gave stegosaurus the ability to thoroughly chew and pre-digest its food before swallowing it and also allowed this dinosaur to pack away more vegetable matter than its non-cheeked competition.

06.           Most Stegosaurs Hailed from Asia, Not North America Although it's by far the most famous, stegosaurus wasn't the only spiked, plated dinosaur of the late Jurassic period. These reptiles have been discovered across Europe and Asia.
