March 21st Meeting

The MGS met on March 21st on Zoom. Among other decisions made during the business portion, it was agreed that the May meeting will also be held on Zoom. Whether future meetings this year will be virtual or in-person is to be discussed in May. It was also decided 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 and New Members

It was agreed at the January 21st meeting that no dues for 2021 will be collected, and that dues paid for 2020 will be applied to a future dues payment. Resumption of dues collection will be determined at a later date. Individuals seeking to newly join the club for 2021 should fill out a membership application form and send it to Treasurer Rob King without paying the $15 membership dues. The application form and Rob's address can be found on the Join page.
