HALL OF RECORDS
Highest & Lowest δ Values by Year
The most common methodology employed by members of the lab is the analysis of stable carbon, nitrogen, and sulfur isotopic compositions by EA-IRMS. Below are the records for the lowest (▼) and highest (▲) delta values recorded by year. The all-time records are indicated with three arrows: lowest (▼▼▼) and highest (▲▲▲).

PEOPLE'S CHOICE AWARD
Voted on by lab members as the coolest sample analyzed in a calendar year.
2017 - 527
Vicacha fleece
A fleece sample made from the hair of the vizcacha. This sample comes from a site in the Pampa del Tamarugal in the Atacama Desert of northern Chile that was occupied by hunter-gatherers ~11,500 years ago.
You can read more about this sample in this paper.
2018 - 604
Narluga
A sample of bone from the world's only confirmed beluga-narwhal hybrid (the 'narluga') from Disko Bay (West Greenland). This specimen is housed at the Zoological Museum in Copenhagen.
You can read more about this sample in this paper.
2019 - 5295
Double-tusked narwhal
A sample of bone from a rare narwhal with two very large tusks. This specimen is housed at the Zoological Museum in Copenhagen.
2020 - 9811
Iron Age dog from Siberia
A naturally mummified dog from the Lower Ob River region in Siberia produced bone, hair, and nails for isotopic analysis. The dog fed on freshwater fish supplied by people throughout the year. You can read more about this sample in this paper.
2021 - 14525
Blue wildebeest
A 42,000 year old tooth from a blue wildebeest. Stay tuned to find out why it was so cool!
2022 - 17885
Thule dog baculum
This Thule dog bacculum (penis bone) had an extremely high δ15N value. It was a part of Brooke Driscoll's MA thesis.
2023 - 21474
African giant buffalo
A 115,000 year old sample from Klasies River Mouth that yielded well-preserved collagen.
2024 - 26181
Bermuda petrel from Jamestown, Virginia
The Bermuda petrel bones from Jamestown (these also produced the highest δ34S value for 2024), which are not native to that region, and would have been brought back to the settlement during the 'Starving Time' of 1609-1610.
