Own Earth's K-Pg Boundary - Famous Geological Event
This dynamic Riker display frames authentic K-Pg boundary material alongside vivid artwork of a Tyrannosaurus rex witnessing the cataclysmic end-Cretaceous bolide. The presentation turns this 1.18 grams of genuine impact-associated ejecta into a powerful miniature science exhibit. It provides a direct, tangible connection to the Chicxulub impact, the sudden collapse of the dinosaur world, and the subsequent dawn of the age of mammals.
Why This K-Pg Boundary Matters
The K-Pg boundary layer represents a revolutionary milestone in modern geology, providing the foundation for the Alvarez impact hypothesis. The material in this Riker display contains the unmistakable physical hallmarks of an extraterrestrial impact event, including global soot, shocked minerals, and elevated iridium concentrations. Studying these regional proximal deposits allows scientists and students to reconstruct the immediate environmental aftermath, including the atmospheric darkening and global climate disruptions that followed the impact.
Collector and Classroom Appeal
Unlike generalized geological samples, this scientist-sourced specimen is directly linked to the terminal Cretaceous impact event. Its distinct texture and composition offer a compelling macro-level narrative of planetary dynamics and deep time. Housed in a secure, attractive, professional presentation format, it ensures long-term stability and effortless integration into classroom lesson plans, interactive seminars, or sophisticated private showcases.

Questions Commonly Asked
What is this specimen?
This specimen consists of authentic geological material from the Cretaceous-Paleogene (K-Pg) boundary layer. It represents rock debris, ash, and sorted target-rock matrix that was thrown into the atmosphere and redeposited following the massive hyper-velocity asteroid impact at Chicxulub.
How did K-Pg material form?
When the carbonaceous or chondritic impactor struck the Yucatan region ~66 Ma, it instantaneously pulverized, vaporized, and melted massive volumes of target crustal rock. This high-energy plume was expelled dynamically into the air and marine basins, rapidly settling into distinctive stratigraphic layers that mark the abrupt boundary between the Cretaceous and Paleogene periods.
Is this good for classroom use?
Yes, it is highly recommended for educational environments. Holding a physical piece of Earth's extinction record dramatically increases student engagement when teaching concepts such as deep time, stratigraphy, mineral shock features, and macroevolutionary transitions.
Add this pivotal Chicxulub event specimen to a serious Earth science collection, classroom display, or museum-style geological exhibit. ONLY 1 AVAILABLE.
This specimen stands as a direct, physical testament to the cataclysmic Chicxulub impact event— preserving a distinct, high-energy record of sediment and debris that fundamentally reshaped our planet's biosphere and marked the end of the age of the dinosaurs 66 million years ago.
