The FedEx Fossil Amphibian
March 16, 2010 | The Guardian

How could a 300 million-year-old amphibian get a name like “FedEx”? Because he was found on land owned by the package carrier. The rare amphibian was found near Pittsburgh by an amateur fossil hunter.

Ocean Extinction and Microscopic Fossils
March 8, 2010 | Penn State Live

Since very small organisms like plankton form the base of the ocean’s food chain, anything that affects them will impact most marine life. Microscopic aquatic fossils are being used to compile latitudinal details on the mass extinction events of 65 MYA.

Pushing Back the Age of Dinosaurs
March 5, 2010 | The University of Texas at Austin

A new fossil discovery was made in Tanzania of a dinosaur-like creature that lived about 10 million years before the first dinosaur. Characteristics of this animal suggest that the first dinosaur might have lived earlier than previously believed.

Darwinius / Ida Not Haplorhine Primate
March 4, 2010 | University of Texas

Scientists from three universities have written papers on how the fossilized primate Darwinius masillae (“Ida”) cannot be classified as a haplorhine – the primate category that contains monkeys, apes and humans. Rather, it is more likely a strepsirrhine – of the branch with lorises and lemurs.

DNA Sequencing of Polar Bear Fossil
March 2, 2010 | Penn State University

Polar bear fossils are not a common find, so information about the bears’ evolution is relatively scarce. Researchers have sequenced the DNA of a Norwegian polar bear fossil, and conclude that the species descended from brown bears, and then evolved notably in the late Pleistocene.

Doushantuo Fossil Bed Geochemistry
February 16, 2010 | UC Riverside

The Doushantuo fossil beds in China have provided some clues about the geochemical complexities of the early ocean. It is possible that in the Ediacaran Period, oceans became sulfidic and then ferruginous at greater depths.

Prototaxites Fossils and Liverwort
February 15, 2010 | American Journal of Botany

Paleobotanists have come up with a new theory about Prototaxites fossils: perhaps the creatures were composed of Paleozoic moss-like mats of liverwort, similar to today’s Marchantia.

Ancient Titanoboa Snake ate Crocodiles
February 10, 2010 | University of Florida

The enormous Titanoboa snake probably ate crocodiles for breakfast, according to fossils from the Cerrejon coal mines of Colombia. The pits contain fossils of the ancient snake and Cerrejonisuchus improcerus, a newly-discovered, crocodile-like species that was around 2 meters in length.

Primate Brain and Body Size Evolution
February 9, 2010 | University of Cambridge

As man evolved, his brain size increased. However, not all primates have developed bigger brains through history; the gorilla, for instance, has grown more in body mass. Researchers at the Universities of Cambridge and Durham are studying brain and body development in primates to help unravel the enigma of the Homo floresiensis, or the “hobbit” fossil, which has a small brain in comparison to modern-day humans.

B. Sealeyi Fossils Rare Find in NM
February 8, 2010 | National Geographic

There is not an abundance of well-preserved dinosaur fossils in the Bisti/De-Na-Zin Wilderness of New Mexico. So, finding two almost-complete members of the T. Rex family there was a surprise. Bistahieversor sealeyi is a new species, and appears to be unique to the area.

Prehistoric Teeth Support DOHaD
February 8, 2010 | Emory University

DOHaD, or the Developmental Origins of Health and Disease Hypothesis, states that the health of a person during early development can predict their longevity. Some prehistoric teeth found in Peru support this hypothesis. Skulls of people who died young were more likely to have striated tooth enamel, an indicator of troubled formation.

New View on Jurassic Primate Evolution
February 2, 2010 | Buffalo Museum of Science

Michael Heads, Ph.D., of the Buffalo Museum of Science, has a theory on primate evolution that differs from most others. He believes that primates did not evolve from one singular location, but were dispersed across Pangaea and evolved in independent groups due to geologic events, such as plate tectonics and volcanic activity.

Australian Megafauna Extinction Debate
January 29, 2010 | University of Adelaide

There has been a long-standing debate on what caused the extinction of some Australian megafauna in the late Pleistocene – was it humans or climate? Direct dating of some fossilized teeth in Cuddie Springs supports the human intervention theory.

Fossilized Tracks Spark Big Theories
January 12, 2010 | Uppsala University

Some fossilized animal tracks in Poland are inspiring some bold theories. Land-roaming tetrapods could have evolved 18 million years before we thought, and coexisted with their elpistostegid fish ancestors for over ten million years.

A team of researchers at the University of Bristol has used micro-tomography to examine the deciduous and permanent teeth of the Lagar Velho skeleton – the skeleton of an early modern human child found in Portugal in the late 1990s. The teeth were compared to those of Neanderthals, Pleistocene humans, and modern-day humans. The findings are summarized in this article.
