"Palpably affectionate...Delightfully improbable adventures plus dinosaurs galore!" -Kirkus

"Mukanik takes extra care in illustrating the various Cretaceous creatures, all of which are marvelously detailed while still maintaining an expressive cartoon quality, and the action-packed prehistoric jungle setting makes for excellent atmosphere and world building. Middle-grade comics fans looking for adventure with accurate depictions of dinosaurs will be very satisfied with this."
--Booklist

"Readers who enjoy manga will like the vivid style of the pictures...The drawings of dinosaurs (and other ancient creatures), as well as the notes in the back on different species, will please the children who are obsessed with these animals and can identify all of the different ones by name...[G]reat for emergent readers...[D]efinitely pick up Lost Time for a young dinosaur fan." - YA Books Central

"[An] incredible middle grade graphic novel that has everything from time travel to a baby pterosaur...It is legitimately a ton of fun. A good old-fashioned survival tale and a fun book to boot." --Elizabeth Bird, Fuse 8, an SLJ Blog

"[A] fun adventure...[T]here's a good mix of action and danger as well as some slapstick humor." - GeekDad
