An exhibit at the Mayborn Museum in Waco, TX. And my dad as a reference for size.
Here's the info on the plaque:
This is the skull of a humpback whale (Megaptera novaeangliae). It weighs almost 3,000 pounds and measures 19 feet in length. The whale was found by Baptist missionary Zachary C. Taylor in Bahia, Basil in 1905. Mr. Taylor purchased the specimen and had it transported by ship and flatbed railcar to Waco, Texas, where it was placed on display in the Baylor University Museum by museum curator John K. Strecker.
Humpback whales may grow up to 48 feet long, and weight 65 tons. They can swim 17 miles an hour and submerge for up to 20 minutes. They are highly acrobatic, lifting their huge bodies completely out of the water when they breach. Living in groups of 20 or more, they migrate seasonally from northern feeding grounds to southern waters where they mate and give birth. The name “humpback” is derived from their tendency to round their backs when diving.
It is estimated the pre-whaling population of humpback whales was 100,000. Today, they are on the U.S. Fish and Wildlife Endangered Species list with a population of less than 6,000.
