As described by their website, "The Waco Mammoth Site sits on more than 100 acres of wooded parkland along the Bosque River. Surrounded by oak, mesquite and cedar trees, the site offers an escape from the modern world and provides a glimpse into the lives of Columbian mammoths.... it is 'The nation's first and only recorded discovery of a nursery herd of Pleistocene mammoths' -- National Park Service."
As we reached the entrance to the building that protects the mammoth excavation, the guide stopped the group, told us where the first bones were found by some hiking teenagers. She told us a bit about the type of mammoths that were there (Columbian mammoths, not the well-known Woolly mammoths). When she asked if anyone had questions again, Jon raised his hand... again. This time, he asked a great question: "How old are these mammoths." What a great question! These were old -- probably over 10 thousand years old.
Overlooking a strange skeleton, we learned from the guide that they were bones from a camel. Yes, an American camel. The guide got us thinking again, asking how many humps an American camel should have. Again, the question was meant for the crowd, but our kiddo showed his thinking. Will raised his hand to answer, "I don't think it would have any humps because it doesn't need to store any food with all the plants here." The guide shook her head amazed that a child would know the camel had zero humps. She started to ask, "Does anyone know WHY the camel had no humps?" when she mumbled the last part because she realized that Will had already answered that part -- there was plenty of food to be had.
After the tour some of the other adults were commenting to us that we had smart kids. They started joking with each other that they wouldn't get very far on "Are you smarter than a 5th grader?" game show. They kind of included us in on the joking, but then kept commenting that our fifth grader knew way more than they did about mammoths. We politely smiled, and as we walked away, we realized the strangers expected Will to be a fifth grader. They were off by a couple of years, but I decided not to point that out.
Some of the things we learned today:
•Columbian Mammoths (Mammuthus columbi) lived during the Pleistocene Epoch (2.5 million years to 10,000 years ago).
•The Columbian mammoth was one of the largest mammals to have lived during the Pleistocene Epoch. Other animals that lived during this time included giant ground sloths, short-faced bears and giant beavers.
•The Columbian mammoth is a distant relative of the Woolly mammoth, but Woolly mammoths stayed farther north in much colder regions.
•Columbian mammoths grew to more than 14 feet in height and weighed up to 10 tons (20,000 lbs). They stood 2 to 4 feet taller and weighed up to 8,000 pounds more than Woolly mammoths.
•A mammoth’s tooth could be as large as a four-pound shoe box. Mammoths had six sets of teeth during their lifetime, which could span up to 75 years.
•The mammoth’s tusks were modified incisor teeth. The tusks grew as long as 16 feet and weighed up to 200 pounds each.
•Mammoths spent up to 20 hours a day eating between 300 to 700 pounds of grass and large fruits. As a result, mammoths produced around 400 pounds of dung a day.
•Columbian mammoths walked on their tiptoes. A sponge-like pad was behind the bones of their feet, which cushioned their immense weight.
