At least I know she is paying attention

Yesterday at the doctor's office Sophie and I were looking at paintings of dinosaurs that kids had painted. She very matter of factly explained to me that I was most likely looking at a picture of a _______. (Fill in the blank with the name of some long necked dinosaur that she knows the exact name of and I don't. ) She was busy explain all the details of the ________, even down the fact that the ______ has nostrils on top of its head to breath while mostly under water to escape from meat eaters, until she hit something that apparently didn't fit in. "The ________ doesn't have those ridges on its back though. Perhaps this is a free form dinosaur." Sophie: the artistic paleontologist.
