Description of Pictures: Walk Among Dinosaurs! Augmented Reality Experience
May 21, 2014 – September 2, 2014
Walk with Tyrannosaurus, Triceratops, and Troodon of the Late Cretaceous, through the use of augmented reality and motion tracking. Visitors see themselves on a large LED video wall allowing them to interact with a variety of dinosaurs including a Triceratops and T-rex. Since its opening weekend, over 340,000 visitors have participated in the experience.
These dinosaurs were among the last dinosaurs that lived in North America just before the mass extinction 66 million years ago. But not all dinosaurs went extinct: birds are the direct descendants of dinosaurs and are related to Tyrannosaurus.

Specific picture descriptions: Photos above with "i" icons next to the bracketed sequence numbers (e.g. " ") are described as follows:
SINHWA_140627_006.JPG: Not Just for Show:
If a striking appearance didn't drive off rivals and predators, Triceratops was equipped for a fight. How do we know? Researchers have unearthed skulls of Triceratops with healed puncture wounds -- evidence that these animals probably used their horns in contests with other Triceratops, much as animals such as rhinos do today.
SINHWA_140627_009.JPG: Look at Me!
Like a peacock's elaborate tail fan, the frill of Triceratops made for a good show. Just seeing a dinosaur with this eye-catching structure would have impressed potential mates and rivals.
Some scientists think the frill might have been colorful, too, and certain horned dinosaurs even had spikes or horns along the edges of the frill.
SINHWA_140627_011.JPG: Small teeth for a Big Job:
Triceratops ate plants -- lots of them -- using its sharp beak to nip off vegetation and a set of continuously replaced teeth to chew tough, fibrous food.
Each tooth was small, and they grew in stacks. The stacks formed long rows in the upper and lower jaws and created large cutting surfaces for crushing and slicing food. Teeth dropped out constantly, so the cutting edges always stayed sharp.
SINHWA_140627_021.JPG: Big Meals mean Big Guts
Triceratops ate and ate and ate, probably both day and night. Living on a diet of plants requires a sizable digestive tract, and the dinosaur's stomach and intestines probably filled much of its barrel-shaped abdomen.
Like cows today, Triceratops probably had countless bacteria and fungi in their guts that helped break down plant cellulose into glucose and other nutrients.
SINHWA_140627_028.JPG: Triceratops horridus
Triceratops horridus is one of two species of Triceratops currently recognized by scientists. It's very rare to find a complete skeleton of any dinosaur because the bones separate as the soft tissue decays, and most are lost over time. Fossils from several individuals went into reconstructing this skeleton.

Bigger photos? To save space on the server and because the modern camera images are so large, photos larger than 640x480 have not been loaded on this page. If you need the bigger sizes of selected photos, email me and I can email them back to you or I can re-load this page temporarily with the bigger versions restored.
2014 photos: Equipment this year: I mostly used my Fuji XS-1 camera but, depending on the event, I also used a Nikon D7000.
Trips this year:
three Civil War Trust conferences (Winchester, VA, Nashville, TN, and Atlanta, GA),
Michigan to visit mom in the hospice before she died and then a return trip after she died, and
my 9th consecutive San Diego Comic-Con trip (including Las Vegas, Reno, Carson City, Sacramento, Oakland, and Los Angeles).
Ego strokes: Paul Dickson used one of my photos as the author photo in his book "Aphorisms: Words Wrought by Writers".
Number of photos taken this year: just over 470,000.
