Take note: it seems a lot happened while you were out. The entirety of the Triassic and Jurassic Periods for one. Not to mention that pesky asteroid, which certainly shook things up a bit. Not to worry: we recorded it all for you right here on these handy sticky notes, which come prepared with all the detail one could ask for about which pesky prehistoric visitors dropped by, and in what era. Not to mention two pads of delightfully dino-shaped sticky notes perfect for hours of dino doodling. Never miss a guest, meeting, or mass extinction period again.
