Dino Doom
time icon 320
language icon English
The Cretaceous–Paleogene (K–Pg) extinction event, which occurred 66 mya, caused the mass extinction of nearly 75% of the plant and animal species on Earth. This event is marked by a thin layer of sediment which can be found throughout the world in marine and terrestrial rocks. The boundary clay shows high levels of iridium, which is rare on Earth but abundant in asteroids.

Mars Rover Sites
English
This visualization is a 360-degree virtual field trip used in the Red Rocks VFT. This visualization contains three views of Mars from three different rover sites. Images collected from each rover are also embedded. An opportunity to explore for iron oxide is also embedded in imagery.
Craters of Earth
English
This visualization is an interactive map used in the Dino Doom VFT. This visualization contains clickable global locations of meteor impacts on Earth and pop up informational boxes. Contained within these informational boxes is a tool to measure the diameter of the crater.
Hell Creek Mammals
English
This visualization is a 360-degree virtual field trip used in the Dino Doom VFT. This visualization contains two views of a Triceratops dig area and two views of a mammal site nearby. A gigapan at the mammal site provides an opportunity to observe mammal bone fossil fragments left behind.
Hell Creek Trike Dig
English
This visualization is a 360-degree virtual field trip used in the Dino Doom VFT. This visualization contains three views of a Triceratops dig area and incorporates labeling of the dig area. Labels point to the K-Pg (Cretaceous – Paleogene) boundary and the rock ages surrounding the boundary.
Oxidation of Rock
English
This visualization is a video used in the Red Rocks VFT. This video contains an explanation of the process of oxidation and how it relates to the formation of red rock in Oak Creek Canyon, AZ.
Shadow Analogy
English
This visualization is a used to demonstrate distance and size of a large light source such as the Sun will determine the size of the shadow the moon will cast upon Earth in the Path of Totality Lesson. This visualization uses a baseball and a light bulb as an analogy to the Sun, Moon, Earth system.
Shadow Sizer
English
This visualization is a widget tool used in the Path of Totality lesson. This visualization contains a dark circle and a slider that can be used for measurement of an object on screen in kilometers.
