Titanoboa, meaning "titanic boa," is an extinct genus of snake that lived approximately 60–58 million years ago, during the Paleocene epoch, a 10-million-year period immediately following the dinosaur extinction event. The only known species is Titanoboa cerrejonensis, the largest, longest, and heaviest snake ever discovered, which supplanted the previous record holder, Gigantophis.

A full-scale model of the snake was unveiled at New York City's Grand Central station before the exhibit opens at the Smithsonian in Washington DC.

The $900 wagyu (Japanese-produced beef) burger was unveiled to commemorate the era change. What’s in a name? Quite a lot if you’re a Japanese citizen awaiting the official announcement Monday, April 1, 2019 of what the soon-to-be-installed new emperor’s next era will be called. It’s a proclamation that has happened only twice in nearly a century, and the new name will follow Emperor Naruhito, after his May 1 investiture, for the duration of his rule, attaching itself to much of what happens in Japan.
