March 21st Meeting
The MGS met on March 21st on Zoom. Among other decisions made during the business portion, it was
agreed that all 2021 issues of the MGS newsletter will be available on the website (see notice at right).
The meeting featured an interesting talk by MGS vice president Eric Seifter on estimating the age of mammoth teeth. Eric took
us through the morphology of mammoth teeth and how they were structured for breaking up the grasses that formed the animal's diet. He described
the development of the teeth in the living animal, including the six sets the animal might have during its lifetime. The method
he described for estimating the age centered on the number of exposed and unerupted tooth plates of an individual tooth.
The talk was based on his article which appeared in the March issue of the MGS newsletter (available on
the Selected Past Issues page).
  No Dues For 2021
No dues will be collected for 2021. Dues paid for 2020 will be applied to a future dues payment.
