Word Wednesday: Australopithecus

Paleontology and paleoanthropology are full of unwieldy scientific names and these names crop up from time to time in news stories. I will be discussing the meaning of the names of three alliterative hominid species: Australopithecus afarensisAustralopithecus africanus, and Australopithecus anamensis.

Australopithecus

Australopithecus breaks down into two parts: australo and –pithecusAustralo comes from the Latin word ‘australis‘ which means southern and pithecus comes from the Greek word ‘pithekos‘ which means ape. Australopithecus is a genus of gracile hominids that originated in eastern Africa around 4 million years ago and went extinct around 2 million years ago.

anamensis

Anamensis breaks down into two parts: anam and –ensisAnam comes from the Turkana word for lake, and ensis is a Latin word which means belong to or originating in. Therefore, Australopithecus anamensis means southern ape originating in a lake. The first fossils were found  near Lake Turkana in Kenya and were named for the region. Fossils have also been found in the Middle Awash of Ethiopia. Australopithecus anamensis lived in East Africa between 4.2 to 3.9 million years ago.

afarensis

Afarensis breaks down into two parts: afar and –ensisAfar is a region in Ethiopia and we already know that ensis means originating inAustralopithecus afarensis therefore means southern ape originating in the Afar. Many fossils have been found in East Africa and fossil sites include those in Hadar (part of the Afar region of Ethiopia) and Laetoli in Tanzania, as well as other sites in Ethiopia and Kenya. Australopithecus afarensis is best known for including Lucy and the makers of the Laetoli footprints. Australopithecus afarensis lived in East Africa between 3.85 and 2.95 million years ago. 

The Taung Child (By Guerin Nicolas via Wikimedia Commons)

africanus

Africanus is the Latin word for Africa, so Australopithecus africanus means southern ape from Africa. Unlike Australopithecus anamensis and Australopithecus afarensis, this species has been found at 4 sites in South Africa: Taung, Sterkfontein, Makapansgat, and Gladysvale. The first Australopithecus africanus fossil was the Taung Child found by Raymond Dart in 1924. The Taung Child was the first specimen to be included in the genus Australopithecus. They lived in South Africa between 3.3 and 2.1 million years ago.

This list only includes some of the gracile australopithecines. There are other species within Australopithecus, as well as the robust australopithecines that have been placed in either Australopithecus or Paranthropus. However, that is a discussion for another day.

To learn more about the species I mentioned above, I recommend the Smithsonian National Museum of Natural History’s Human Origins website. If you want to learn more about human evolution, I highly recommend John Hawks’ blog.

Abolished parks, the Kraken, and dead plants: Geological Society of America’s 125th Annual Meeting

I was lucky enough to spend the better part of last week at the Geological Society of America’s 125th Annual Meeting in Denver, Colorado. This was my first conference and it was an amazing experience!

My flight to Denver can be described with one word: mountains. I left the ancient Appalachian Mountains in Tennessee for the younger, taller Rocky Mountains in Colorado. The views were beautiful and the temperature in Denver was much more pleasant than what I had left in Tennessee!

Some of the exciting things I did:

On Monday, I presented my talk  ‘Paleoclimate Reconstructions of Three Mid-Atlantic Miocene Sites’ in the session Quantitative Reconstructions  of the Large-Scale Cenozoic Climate Change.

I met Dave Marshall of Palaeocast fame and he interviewed me about my paleoclimate research. On Tuesday we had the opportunity to interview Drs. Bob Bakker and Matt Mossbrucker. If you check out the Palaeocast recap of the conference, you can hear me talk about my research at ~21:05 on Day 2 and on Day 3 at ~14:48 you can hear Dave and I talk to Drs. Bakker and Mossbrucker about the tale of the Brontosaurus.

I really enjoyed Dr. Holly Dunsworth’s talk ‘The Sub-Saharan Origins of Cercopithecoids, Hominids, Hominins, and Humans‘. It was nice to have a little biological anthropology sprinkled in amongst the geology!

On Tuesday night the Denver Museum of Nature and Science was open after hours to students at the GSA conference. It’s a fantastic museum and I highly recommend visiting. I especially enjoyed the Prehistoric Journey exhibit.

At the end of the conference, I went to Dr. Mark McMenamin’s talk ‘The Kraken’s Back: New Evidence Regarding Possible Cephalopod Arrangement of Ichthyosaur Skeletons‘. The room was packed and there was even a film crew! Dr. McMenamin is a fantastic speaker and the presentation included beautiful artist reconstructions, but overall I was not convinced that there was evidence of Kraken attack and subsequent arrangement of bones.

Some of the interesting things I learned:

For me, the first morning of the conference was dominated by the session Geology in the National Parks: Research, Mapping, and Resource Management I. I learned about Fossil Cycad National Monument, a former national monument in the Black Hills of South Dakota that was removed from the National Park System in 1957.

I made sure to attend Dr. Benjamin Burger’s talk ‘Mammal Species Durations in the Fossil Record: Answering the Question, Which Species has the Longest Duration in the Fossil Record?‘. The answer was the fossil insectivore Centetodon magnus. I was pleasantly surprised that a Gomphothere came in second place!

The session Dinosaurs & Diamonds: 125 Years of Geoscience in Museums started with the talk ‘Let’s Talk About Rex, Baby: Communicating Science and the Myth of Dumbing Down‘. Dr. Richard Kissel addressed the idea that museums ‘dumb down’ their material for the visitors. This is not necessarily, and should not be, the case. Instead, it just takes a different way of presenting the information.

On Tuesday afternoon I went to Richard Harris’s (of NPR) talk ‘Why People Trust Scientists but Not Science: Climate Denial in Context’. He talked about the fact that most scientists believe that the lack of acceptance of science (particularly with respect to climate change) stems from the absence of information. Instead, it likely stems from different moral priorities as well as a misunderstanding of how science works.

All in all, the GSA Annual Meeting was a great experience. I met some interesting people, learned some geology and paleontology, and had the chance to miss classes to spend a week in Denver! Hopefully I’ll get the chance again next year!
