"Whaaaaaat?" Did you know that wooly mammoths have never been recovered from the La Brea Tar Pits? The mammoth on display in the museum (pictured here) is a Columbian mammoth—their larger cousin named for Christopher Columbus. #themoreyouknow #tarpits #iceage #Pleistocene #paleontology #latergram

One hundred years ago today, Martha, the last living passenger pigeon, died and marked the extinction of one of the most abundant species on the planet.

Today, I visited the lone pigeon in our Bird Hall at the Natural History Museum (@nhmla). Powerful emotions come when you look at an animal that no longer exists because of our species.

Abundance is not immune to extinction.

Red algae in the @labreatarpits Lake Pit? This needs to be investigated! So curious…#science #tarpits #ecology #lovemyjob

I like monarch butterflies. They’re beautiful, poisonous, and only eat sugar. #myspiritanimal #nofilter
