About This Project

We are working on a special open-access volume dedicated to the famed diplodocoid sauropods (like Diplodocus). We aim to publish several papers describing their anatomy, osteology, evolutionary relationships, biogeography, and more. This project will result in publicly available datasets coupled with all the contributing papers being free to access. Thereby, we’ll contribute to Open Science, which is crucial towards sharing data around the world and providing resources for other scientists.

What is the context of this research?

Diplodocoid sauropods are amongst the most iconic dinosaurs of all, including Apatosaurus, Diplodocus, Supersaurus and even the enigmatic Nigersaurus. In the last 150 years, an incredible amount of specimens have been found of this group, leading to many different species from various geological time periods. However, much of their evolutionary relationships remains uncertain, which in turn affects our knowledge about their ecology and biogeography.

By describing new specimens and redescribing old specimens in a special volume dedicated to diplodocoid sauropods, we aim to better understand their relationships, ecology and biogeography.

What is the significance of this project?

This volume will centralize a number of ongoing projects of an international collaboration on various diplodocoid sauropod specimens at the journal Palaeontologica Electronica which is open access and free for all, as well as a final project focusing on the evolutionary relationships of all these new and older specimens. This can help us understand how each diplodocoid clade evolved, how they are related, what their ecological role was, and how they are biogeographically distributed.

What are the goals of the project?

The publications in this special volume will cover a variety of topics, including the description of novel specimens, including new species, as well as the redescription of older species. We also plan to conduct a phylogenetic analysis using morphological characters such as the absence/presence of anatomical traits to test the evolutionary relationships between all new specimens across all diplodocoid families, coupled with a biogeographical analysis of how these sauropods diversified across the globe through time.

We promise to mention the names of the backers in the acknowledgements of at
least one upcoming paper, if this campaign is successful.

Budget

Please wait...

This special volume is being hosted by Palaeontologica Electronica, an open-access journal that usually doesn’t charge an Article Processing Charge (APC). However, they are providing additional effort for submission handling, copy editing and other services for manuscript submission to this special volume, on top of their usual day-to-day work for normal submissions. To account for this, they are charging a $3000 USD APC. The money raised here will go towards paying the APC, and any extra money raised beyond the required $3000 will be used to commission pieces from paleoartists to be used in the various volume papers.

Endorsed by

The special volume on Diplodocoidea represents an excellent opportunity to expand our knowledge of the group. The open-access format ensures that anyone, anywhere in the world, can engage with and stay up to date on this remarkable project. I am delighted to endorse this initiative and look forward to reading the forthcoming publications.
I am so excited to see the numerous parts that will comprise this volume. Written by the leading experts in the field today, replete with fantastic images, wonderful descriptions, and insightful observations, this book will be the “go-to” for diplodocoids for decades to come!
In 2015, Tschopp and coauthors published a massive paper that set the program for a decade of progress on diplodocoid evolution. Now a dream team of paleontologists -- including established experts and early-career investigators at the bleeding edge of sauropod research -- has assembled to produce an even more comprehensive and collaborative leap forward on this fascinating, long-lived, globally-distributed group of dinosaurs. I look forward to reading and relying on this publication in my own future work, and I'm happy to endorse this project.
The project team shows a great expertise on diplodocoid sauropods, a wonderful group of sauropod dinosaurs. The option to publish open access allows potentially to enhance common knowledge and the project leaders might also catalyze more scicomm. I look forward to the potential paleoart and the progress of the project.
This is an important group of research papers in vertebrate palaoentology, conducted by a group with a solid track record. The initial set of as-yet-unfunded papers from this project are excellent: informative, accessible, significant. The small amount of required funds does not support the work itself, but its publication in an open access venue to ensure that anyone, anywhere in the world, can read and re-use the results. I think this is great.

Cary Woodruff

I am the Curator of Vertebrate Paleontology at the Phillip and Patricia Frost Museum of Science in Miami, Florida, and I specialize on sauropods of the Morrison Formation. In particular, I am interested in sauropod ontogeny (changes in the skeleton as the animals grew up), and I use a combination of morphology (shape of the skeletal features) and osteohistology (microscopic anatomy of the bones) to document not only how old an animal was when it died, but when various changes in the shapes of the bones occurred in life. Documenting when and why such changes occurred can help us better understand the life histories of these remarkable terrestrial titans.

Andrew Moore

I am evolutionary anatomist at Stony Brook University that studies the evolution of sauropod dinosaurs and their living cousins, birds. My lab uses a diverse toolkit to reconstruct the phylogeny of these groups and to test hypotheses about the evolution of the axial skeleton and the soft tissues that shape it. I am particularly interested in the evolution of exceptionally long necks in mamenchisaurids, diplodocoids, and other sauropods, and in characterizing the macroevolutionary shifts in scaling that produced their remarkable body plans.

Tom T.P. van der Linden

I am a research associate at the Oertijdmuseum, the Netherlands, specializing on sauropods, primarily diplodocoids, and dinosaur eggs and the evolution of reproductive strategies in Archosauria. Through studying new specimens and their biogeography, we can learn so much more about the iconic sauropod group including Diplodocus and Apatosaurus.

Emanuel Tschopp

I am a vertebrate paleontologist at Freie Universität Berlin, Germany, specializing on sauropods from the Morrison Formation. During my PhD I have created a specimen-level phylogenetic matrix of diplodocid sauropods to reassess taxonomy and systematics of this clade. One of the results was that we considered Brontosaurus valid again, after more than 100 years of oblivion. It’s now 10 years since publication of that study and time to check all that with new data and new exciting specimens.

Colin Boisvert

I am a PhD Student at the Oklahoma State University Center of Health Sciences studying theropods. I have conducted some research on Haplocanthosaurus in the past and did my masters at BYU on sauropod neck biomechanics, working with an apatosaurine specimen. I have loved dinosaurs since I was a little boy and decided I wanted to become a paleontologist. I love field work and am fascinated by questions such as how so many large-bodied sauropods lived in the Upper Jurassic Morrison Formation. I believe studying dinosaurs is important as they are an excellent case study group to explore the extremes of evolution, responses to climate change, and extinction events.

John Whitlock

I'm an Associate Professor in the Dept of Science and Maths at Mount Aloysius College and a Research Associate at Carnegie Museum of Natural History. I study the systematics and paleoecology of sauropod dinosaurs, specifically the diplodocoids of the Late Jurassic Morrison Formation. My research focus is currently on investigating the hidden taxonomic diversity these animals by re-evaluating specimens previously collected but not described.
