MACK at the Smithsonian Natural History Museum

Last week during the Cherry Blossom Festival in Washington D.C., our family took a trip to see the beautiful trees and to visit one of the Smithsonian Museums.  Click here to read about our visit to see the cherry blossoms. 

Mackenson's visit to the Smithsonian Natural History Museum in Washington D.C. provided him with the opportunity to study the timeline of Earth's history.  He saw fossils, models and reproductions from the Precambrian time period, Paleozoic Era, Mesozoic Era and Cenozoic Era.  For his project he was asked to make a one page presentation or mini poster for each of these major time periods.


The jellyfish in a diorama displaying the Precambrian time period caught Mackenson's eye.

Veering away from animal life, Mackenson chose to look closely at the sphenophyllum (spore producing plants) that grew in the Paleozoic Era.

Mackenson liked the Trilophosaurus, a lizard that lived in the Mesozoic Era. 

Uiuntatheres was an early mammal in the Cenozoic that Mackenson was interested in.
