Cretaceous Caretaker: Rex Finds An Egg! Egg! Egg! by Sten Weinberg
When this goofy-looking baby dino finds a large spotted ovoid, he assumes it's an egg. He's quite taken with it and carries it carefully toward his own nesting area.
But prehistoric times are fraught with danger. A nearby volcano begins to rumble and spout, and Rex realizes he has to do something to save himself--and his egg.
"RUN! RUN! RUN!"
Rex makes a run for it, unfortunately right over a cliff and into the cretaceous sea, swimming with a variety prehistoric critters. Luckily, Rex lands on the back of one sea monster and seems temporarily safe.
But, NO! A pterodactyl swoops to scoop up Rex and egg. Rex slides down the sea monster's back and scurries back to the safety of his own nest. Whew!
But when the volcano again begins to shake the earth, spewing steam and lava, little Rex drops his prize. It cracks open, and Rex realizes that he's been nurturing, not an egg at all, but a rock! Rex is briefly brokenhearted. Is this the sad end to a possible lovely friendship?
Little Rex is an appealing little predator in Steven Weinberg's jolly T. Rex romp, Rex Finds an Egg! Egg! Egg! (Margaret K. Elderry Books, 2015. Weinberg's easy text will have tots chiming in on the thrice-repeated refrain and older preschoolers will soon be "reading" this one themselves, while his bright palette shows off his cute little T. Rex character with plenty of charm and verve.
But Nature will out, as caretaker turns carnivore when Rex gets a bit rumbly in his tumbly and spots potential herbivorous prey:
"LUNCH! LUNCH! LUNCH!"
As Kirkus Reviews adds waggishly, "Young dinosaur fans will like this solo debut for Weinberg a bunch, bunch, bunch."
