HOUSTON --It's that time of year when the spotlight is put on biggest beasts in the sea. It's Shark Week! This year, you can get up close and personal with a shark, without having to get in the water. The Discovery Channel's annual event kicked off Sunday night. So all this week, the Houston Museum of Natural Science is getting in on the exploration. The museum's associate curator of paleontology will construct an 11-foot wide Megalodon jaw. The Megalodon lived 25 million years ago. It makes the Great White sharks of today look like goldfish. You can watch the reconstruction of the fossilized jaw every day this week from 1pm until 4pm at the HMNS.
