  • PRI staff and hundreds of volunteers helped unearth the entire skeleton

  • Excavation lasted six weeks

  • The Hyde Park specimen was determined to be an American mastodon (Mammut americanum)

  • Probably an adult male 30 – 40 yrs old

  • May have weighed as much as 10,000 – 15,000 lbs (4,500 – 6,800 kg)

  • Lived around 11,500 BC

  • Other research focuses on:

    • sediment charcoal

    • ostracodes

    • plant macrofossils

    • taphonomy

    • beetles

    • stable isotopes of sediments and mastodon teeth

    • sedimentology/stratigraphy

Hyde park mastodon6
Hyde Park Mastodon Collections

  • Remnants of at least ten species of trees are represented in the sediments that lined the bottom of the ~18,000 yr-old pond

  • Many of these species no longer live around Hyde Park, but can be found near Hudson Bay in north central Canada

  • Can we find more?

  • The PRI’s newest venture

  • Much smaller than the Hyde Park mastodon

  • Cranium was fragmented (very common occurrence, perhaps due to hunters attempting to make use of the entire kill)

Middle school students as researchers
Middle School Students Collectionsas Researchers

  • Middle school students in East Tennessee are participating in the Mastodon Matrix Project as part of the GK-12 Program

  • Examination of the matrix provides a unique method for meeting state science standards

Tn curriculum framework connection
TN Curriculum Framework Connection Collections

Content Standard: 6.0 Biological Change

The student will understand that living things have changed over time.

Learning Expectations:

  • 6.2 Recognize various forms of evidence which indicate that life forms have changed over time

  • 6.3 Reason how environmental changes are associated with the extinction of a species

Materials produced by the University of Tennessee GK-12 Earth Project, funded by the National Science Foundation GK-12 Program under grant # DGE-0538420.


State performance indicators
State Performance Indicators Collections

  • As documented through state assessment,

    at Level 1, the student is able to:

  • 6.6.spi.1 analyze how fossils provide information about the past

  • 6.6.spi.2 identify factors that contribute to extinction.

Materials produced by the University of Tennessee GK-12 Earth Project, funded by the National Science Foundation GK-12 Program under grant # DGE-0538420.


Teacher performance indicators
Teacher Performance Indicators Collections

  • As documented through teacher observation,

    at Level 2, the student is able to:

  • 6.6.tpi.2 compare and contrast the different processes of fossil formation.

  • 6.6.tpi.4 collect and/or observe various fossils and relate them to biogeographical changes.

Initial results
Initial Results Collections

  • Six classes at Carpenters Middle School, Maryville, found 861 items in ~3,000 cc of matrix. Students found:

    • 743 plant macrofossils (twigs, fragments of tree bark, seeds and conifer needles)

    • 116 rocks

    • 2 shells

  • All items and data will be sent back to Ithaca, NY, where they will be cataloged by PRI and Cornell paleontologists

  • We plan to share this activity with nine other middle-school teachers in the Knoxville area
