Tony Martin Interview, Part 2
by Andrew Farke in The Open Source Paleontologist
Yesterday, I ran the first part of this two-part interview with Anthony (Tony) Martin, senior author on a new paper in PLoS ONE. The research details a rare trace fossil (figured below) left behind by a bottom-feeding fish over 50 million years ago. Yesterday's questions focused on the science - in the final installment, we'll learn more about the publishing process. (Full disclosure: I am an editor for PLoS ONE, and was the editor who handled this manuscript.)Why did you choose PLoS ONE as a ve........ Read more »

Something Fishy in PLoS ONE (and it's pretty neat!)
by Andrew Farke in The Open Source Paleontologist
The open access journal PLoS ONE has published a lot of neat paleontology articles over the last few years (see here for a reasonably comprehensive listing). Charismatic, terrestrial vertebrates (whether dinosaurs, Ice Age mammals, or prehistoric humans) seem to dominate. But what about the poor, neglected fish?
Today, PLoS ONE published a nifty article by Anthony (Tony) Martin [pictured at left] and colleagues, discussing a 50 million year old fish feeding and swimming trace fossil from Wyomin........ Read more »

Welcome, Seitaad!
by Andrew Farke in The Open Source Paleontologist
I am pleased to announce the publication in PLoS ONE of Seitaad ruessi, a new sauropodomorph dinosaur from the Lower Jurassic Navajo Sandstone of southern Utah. Sauropodomorphs are (mostly) herbivorous dinosaurs that lived from the Triassic all the way until the end of the Cretaceous. Although most people know the giant quadrupedal sauropodomorphs like Brachiosaurus and Apatosaurus ("Brontosaurus"), many of the early sauropodomorphs were bipeds smaller than humans. Seitaad fits in the latter cat........ Read more »

Four-Winged, Psychedelic Dinosaurs
by Andrew Farke in The Open Source Paleontologist
When many of us think of viewing things under a "black light," we either think of those psychedelic posters from the 1960s or else the displays of fluorescent minerals that nearly every science museum has. It's also virtually mandatory to have a scene involving the use of "black light" in the popular CSI television programs - many bodily fluids show up nice and pretty under these conditions. "Black light," more properly known as "ultraviolet (UV) spectrum light", is just outside the visible ligh........ Read more »

Where is paleontology?
by Andrew Farke in The Open Source Paleontologist
Last week, many of the leading journals in evolutionary biology - including The American Naturalist, Molecular Ecology, Journal of Evolutionary Biology, Evolution, and a number of others - announced a data archiving policy. In short, this policy states that the data behind the results of a paper should be publicly archived in well-known respositories such as Data Dryad, GenBank, or TreeBASE. Do you notice anything missing in this illustrious list of publications?Not a single one of those journal........ Read more »

A Happy Family of Pachycephalosaurus
by Andrew Farke in The Open Source Paleontologist
Distinguishing the skulls of juveniles and adults of the same species, and sometimes different species, can be a prickly thing in the fossil record. The result is that paleontology is littered with juvenile fossils that have been considered adults at some time or another. The crested duck-billed dinosaur Corythosaurus has also been known under names like Procheneosaurus, the famous Monoclonius is actually a juvenile of adult Centrosaurus, Styracosaurus, and kin, and the debate still continues on........

An Australian Dinosaur Extravaganza
by Andrew Farke in The Open Source Paleontologist
The Cretaceous of Gondwana - the formerly connected southern landmasses of Antarctica, Australia, South America, Africa, India, Madagascar, and Arabia - is a sticky problem. The terrestrial fossil record is spotty at best in most locations, and tremendous geographic and temporal gaps remain. As a consequence, there is considerable debate about the sequence of the tectonic breakup of Gondwana and even the very identity and relationships of some of its dinosaurs and other Mesozoic beasts. Once in ........ Read more »

How Big (Dead) Mammals Respond(ed) to Global Warming: Paleontology and Our Climate Crisis
by Andrew Farke in The Open Source Paleontologist
After all of the commotion over "Ida," I'm happy to point out a new, thought-provoking paper in PLoS ONE that perhaps has more relevance to modern humans than any old primate of debated affinity. This new contribution ties two rather cool issues together: charismatic megafauna and global warming. And what might they have to do with each other?Within the scientific community, our current cycle of climate change ("global warming") is pretty well-supported by numerous lines of evidence. In light of........ Read more »

About That Adapid. . .Or, Hype In the Digital Age
by Andrew Farke in The Open Source Paleontologist
Today's PLoS ONE includes an article on a new primate from the Eocene of Germany, Darwinius masillae. Poor Darwinius has suffered heaps of abuse over her existence (we know the specimen is probably a she, based on the lack of a baculum). She died young, possibly suffocating during a belch of noxious gas from a volcanic lake. She got squashed ("lightly crushed," as her describers euphemistically say) under tons of rock, and then was rudely given a split personality upon her discovery. Each half o........ Read more »

Albatross vs. Pterosaur
by Andrew Farke in The Open Source Paleontologist
Today, there was a paper tangentially related to pterosaurs in the open access journal PLoS ONE. A team of investigators wired up albatrosses and petrels with accelerometers, in order to measure the percentage of time these animals spent flapping their wings and soaring. They found two main styles of wing flapping (as inferred from the accelerometer measurements): 1) high frequency flapping during take-off; and 2) low-frequency flapping during soaring. Interestingly, the frequencies scale with b........ Read more »

Bone-ing Up on Allometry
by Andrew Farke in The Open Source Paleontologist
Allometric scaling - roughly defined, when different parts of an organism grow at different rates - is an important factor in biology. In part, allometry describes how babies have relatively larger heads than adults (we exhibit negative allometry in this trait, because our skulls don't grow as quickly as the rest of the body) or how some crabs have gigantic claws (an example of positive allometry, in which the claw grows much faster than the rest of the body). Allometry (and its counterpart isom........ Read more »

Crouching Theropod, Hidden Dragon
by Andrew Farke in The Open Source Paleontologist
Fossil footprints (falling in the general category of "ichnofossils") reveal a wealth of information about dinosaur biology, such as speed, posture, and behavior. These traces are particularly useful when offering information independent from, but consistent with, hypotheses derived from purely anatomical studies.Today, a new paper in the open access journal PLoS ONE presents an unusual set of theropod (meat-eating dinosaur) ichnofossils from the Early Jurassic-aged Moenave Formation of southwes........

Triceratops Combat?
by Andrew Farke in The Open Source Paleontologist
Exactly how did Triceratops and other horned dinosaurs use their cranial weaponry? Today, my co-authors Ewan Wolff, Darren Tanke, and I published new research in the online, open access journal PLoS ONE, giving our take on the issue. In a study spanning four years and over a dozen museums, we have marshalled what we think is the best evidence to date that Triceratops may have locked horns with their own kind.Restoration of Triceratops in horn-to-horn combat.
