Specimen ZPALWr. A/4005 from SE Poland
Look out the nearest window and try and spot a bird. While the PE blog audience is joining me from multiple continents and environments, it’s likely that no matter where you are, the bird you see is in the order Passeriformes. This order includes more than half of all extant bird species in the world, including the well-known songbirds. What makes a bird a member of the Passeriformes order? There are a bunch of technical, complicated characters that distinguish passerines from other birds, but one feature that is significant has to do with the arrangement of the toes. Passerines have an anisodactyl arrangement of toes, meaning that three digits point forward while one lone digit (hallux) points backward.

Back in December Edward Davis and Brianna McHorse published a paper in Palaeo-Electronica (PE) about using astragali to identify camel genera from the Thousand Creek locality in Nevada. They have written their own blog post about this research, which can (and should) be read here; though I’ve included an excerpt from their blog to introduce their research to the PE blog audience:
“Many Miocene fossil sites are full of camel ankle bones (and ankle bones of other animals, too, but you have to start somewhere!). Ankle bones are small, compact, and extremely durable. They are also in a part of the animal that doesn’t have much tasty, tasty meat. As a result, they often escape significant damage from banging against rocks during transport before burial or by scavenging…
…Most fossil mammals are identified by looking at details of the skulls and teeth. At some sites, like Thousand Creek in Nevada, skulls are extremely rare but ankles and other foot bones are super common. If we want to know what camels lived in Thousand Creek 8 million years ago, skulls are not enough. Instead, we need to be able to identify all of these ankle bones. At a basic level, this lets us know what kind of camels lived there, but that’s important for more than just paleontological trivia. Those little bits of data go into larger-scale studies of evolutionary and ecological dynamics. Each time we increase our knowledge of a single fossil site, we add another brick to the foundation of our largest-scale analyses, improving our ability as a species to predict how our earth’s fragile ecosystems will behave as we turn up the thermostat.”
So how do you identify ankle bones?

The new zotero 3.0 comes with updated styles, but the conversion caused some errors. Furthermore, the changes we made to the PE style had not been implemented. That’s all fixed now, and you can get the new, correct style here (zip file, 9 kb). On the zotero site it will also soon be available.
This place has been quite as a grave for a long time. That downtime was caused by a number of factors, most significantly the simple fact that I was totally overworked, and that my blogging time went to my own, personal blog.
Additionally, PE was totally revamped, and a lot of papers came out of our backlog caused by last year’s special issue. Add to that a number of papers where authors’ revisions took a long time, which also made it to publication, and there simply was very much work to do for all involved, including the style editors, Daniela Schwarz-Wings and me.
Now, though, I hope to revive the blog, with a series of overdue articles.
Carleton University Awards Graduate Students $1000 for publishing in open source journals
by Timothy Patterson, professor of geology at Carleton University. Tim is a former PE editor, and staunch supporter of open access publishing.
Fifteen years ago Palaeontologia Electronica made history when it became the world’s first fully electronic, open access paleontological journal. Free of the restrictions of the printed page PE remains a pioneer in electronic publishing. Although most journals are now available online, PE’s earth science peers continue to lag PE as most only publish an electronic copy of the print journal. PE permits authors to embed movies, animations, computer programs and other media not possible in a print journal. When we were establishing PE we wanted to set ourselves apart from our peers on another front, by making the journal a freely accessible open source publication with no subscription or access fees. This was important to us as the subscription fees for publications put out by the major commercial publishing houses were straining library acquisition budgets.
Fifteen years later, the journal fees charged by these organizations are straining library budgets more than ever. To encourage young researchers to adopt the new open source, open access publishing paradigm begun by PE, Carleton University has begun offering scholarships to graduate students who publish in open source journals. Sponsored by the Graduate Students Association (GSA), the Library, and the Office of the Vice President (Research & International) the Carleton University Scholarly Communications Selection Committee annually selects the five best research papers published by graduate students in peer-reviewed open access journals to be recipients of a $1000 CAD Graduate Student Open Access Award.
Lisa Neville won a Graduate Student Open Access Award
with her publication in Palaeontologia Electronica
Lisa Neville is one of this year’s recipients, in recognition of her 2010 PE paper “Seasonal environmental and chemical impact on the amoebian community composition in an oil sands reclamation wetland in northern Alberta” (PE Article Number: 13.2.13A). In addition to being available free of any charge at the PE website, the paper will be made freely available through archiving in Carleton’s new institutional repository (CURVE), which is mandated to collect, preserve and make accessible Carleton’s digital research materials. To encourage more graduate students to publish in open source journals the awards will be made at a publicized award ceremony later this spring. Awardee bios and other publicity material will also be placed on the university web site.

Congratulations to Lisa Neville for writing an excellent research paper and publishing it in Palaeontologia Electronica as well as to Carleton University for launching such a proactive initiative. Hopefully other universities will soon follow suit making open source journals a more attractive venue for young researchers to publish their research results.
