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.

I love well-behaved spiders! They are, in fact, how most people find my site. Unfortunately, my network has a limited bandwidth and pictures take up bandwidth. Spiders ask for lots and lots of pages and chew up lots and lots of bandwidth which slows things down considerably for regular folk. To counter this, you'll see all the text on the page but the images are being suppressed. Also, some system options like merges are being blocked for you.
Note: Permission is NOT granted for spiders, robots, etc to use the site for AI-generation purposes. I'm sure you're thrilled by your ability to make revenue from my work but there's nothing in that for my human users or for me.
If you are in fact human, please email me at guthrie.bruce@gmail.com and I can check if your designation was made in error. Given your number of hits, that's unlikely but what the hell.

Specific picture descriptions: Photos above with "i" icons next to the bracketed sequence numbers (e.g. "[1] ") are described as follows:
1. 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.
2. 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.
3. 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.
4. 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.
5. 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.
6. SINHWA_140627_046.JPG: It was a cute interactive display where you interact with the dinosaurs on the screen.

Bigger photos? To save server space, the full-sized versions of these images have either not been loaded to the server or have been removed from the server. (Only some pages are loaded with full-sized images and those usually get removed after three months.) I still have them though. If you want me to email them to you, please send an email to guthrie.bruce@gmail.com and I can email them to you, or, depending on the number of images, just repost the page again will the full-sized images.
Connection Not Secure messages? Those warnings you get from your browser about this site not having secure connections worry some people.
