Boys Find Mastodon Bone Along Stream in Macomb County

It’s nearly every young, adventurous boy’s dream to stumble upon prehistoric artifacts while playing in their backyard.

For an 11-year-old Shelby Township boy, Eric Stamatin and his cousin Andrew Gainariu, 11, that dream came true this summer.

The boys found a mastodon bone while exploring a stream on 24 Mile and Dequindre roads.

“At first it just looked like a rock but it had a hole in it so we thought maybe it was a bone,” said Stamatin.

The boy’s family sent a picture of the bone to Cranbrook Institute to be examined. John Zawiskie geologist with Cranbrook later identified it as the axis bone of the extinct American Mastodon.

“The axis is one of two specialized vertebrae that secure the head to the vertebral column, and judging from the size of this find the animal was probably an adult around 8 or 9 feet high at the shoulders and weighing roughly 6 tons,” said Zawiskie.

The mastodon bone is likely between 13,000 and 14,000 years old. The boys led an archaeological team from Cranbrook back to the spot where they found the bones, but no more artifacts were found.

The stream where the bone was found, near 24 Mile Road and Dequindre, cuts through sand and gravel of an old glacial lake plain and is very near the source of the Middle Branch of the Clinton River. Stephen Pagnani with Cranbrook Institute said mastodon bones are normally found near boggy areas and where there is a lot of sand and gravel.

Mastodons are furry elephant-like mammals, and are close relatives to the woolly mammoth.

They lived about 3.7 million years ago until it became extinct at the end of the last glacial period around 10,000 years ago.

Zawiskie said this is the fourth record of the American Mastodon to be found in Macomb County. Nearly 2/3 of an American Mastodon was found on Adams Road in Rochester in 2006. Road crews unearthed a three-pound molar, tusk and leg bone, among other bones.

“It’s a common archaeological find, but it’s still a fun one,” said Pagnani.

Stamatin, a Roberts Elementary School student, will be showcasing his great find at school on Friday, according to Utica Community Schools. Pagnani said the bone is the boys to keep.

More than 211 mastodons have been discovered in the southern portion of the Lower Peninsula and it is Michigan’s state fossil.
