A dramatic portrait gallery of some of our planet's former residents down through the eras, with pithy odes in rhymed or free verse...Many of the informal facts and observations he adds at the end are just as memorably phrased. Highlights from life's last 544 million years infused with humor and wonder.

It’s not just dinosaurs profiled here; the book heads all the way into the Quaternary period (that’s the one we’re currently in) and introduces creatures like the saber-toothed tiger (“Smilodon”) and the Woolly Mammoth (“Mammuthus”). . . A journey into the past that’s a visual and linguistic joy.

. . . and this wonderful combination of art, poetry, and science is a great addition to libraries.

In this terrific picture book for 3- to 7-year-olds, we see the coiled terror of the snaky Titanoboa, a mist of blood around his attacking jaws. And here is the nightmarish Yutyrannus, feathered like a chicken and built like a T. rex. David Elliott has written captivating odes, at turns jaunty and wise, for each animal.
