Digital Innovation in 2000

I was looking back at field notes and photographs from the “Dinosaur Expedition 2000” online web updates. These images and written notes and labels all contain important data that was obtained during the two week long collection of new dinosaur bones at the site.

The project proved to be innovative in the level of online engagement, with daily written updates and photographs provided on the website of the Fundy Geological Museum in the evening after a full day’s work in the hot sun. The images were taken as Polaroids (R) – the fastest way to develop, scan, and publish images online at the time. Digital cameras were around but not yet quite affordable for regular field work.

This was very early days of the internet – and this was an early example of online updates during dinosaur digs. These updates are still available online through the Way Back Machine.

Expedition Notes: July 21, 2000

The July 21 update is helpful – as it includes an image of the ilium that had been exposed that day. This is the earliest photograph of the specimen (FGM998GF13.46) – a right ilium that has several fault offsets cutting through the bone.

The images in the web updates were very small (8 kb) – because the early internet was very slow and images had to be kept small to avoid long page loading delays.

Years, later – back in the Preparation Lab at the Museum, the specimen was photographed several times while being prepared, and the sandstone was carefully removed away from the fossil bone. In these later years the digital images increased in size and quality as camera technology increased.

Finally, after the bone had been fully prepared – it was then illustrated in a figure with the posterior portion of the ilium blade ‘reattached’, and published in a dissertation in 2007.

The online publishing of the updates from the dinosaur field work was innovative for the early days of the internet. Even twenty years later, these online updates continue to provide information to compliment the field notes, maps and photographs from the dig.

News Publication Updates

Updating the Quarry Map

It was in September 1997 that I first traveled to Nova Scotia to begin my study of dinosaur skeletons at Wasson Bluff. I then spent the next ten years collecting new specimens, and completed my PhD dissertation describing what is now recognized as a bone bed of sauropodomorph (long necked) dinosaurs. Now, twenty-five years later, I am returning to the work to produce new publications that describe these important specimens.

My initial attention is focused on a specimen within the bone bed that is likely to be a holotype. The specimen (GF13-11) includes a partially disarticulated skull, articulated cervical, dorsal, sacral and caudal vertebrae series, pectoral girdle (scapulae, coracoids, clavical, sternal plate), humerus, pelvis and right rear leg.

The 200 million year old dinosaur skeletons are deformed by many faults. The faults cutting the skeletal elements are sometimes be complex and obliterate important details. However, the faults are important part of the context of the bone bed – located in a depositional setting located along a palaeoscarp formed by the Cobequid Chedabucto fault system of the Fundy Basin.

The dinosaur specimens were collected over multiple years (see Field Work) and it is only after the large blocks were prepared that we could develop a clear picture of how the multiple skeletons are laid-out.

One of the initial tasks for the new publications is to create an updated quarry map that summarizes ten years of field work and locates the potential holotype specimen within the bone bed deposit.

The updated quarry map is being produced using Adobe Illustrator, importing field maps (1998, 2000, 2004) and photographs of prepared blocks. Each of the unique skeletons will have a different colour, and the final figure will summarize the layout and faulting of the skeletons.

Tips for Students/Learners:

These types of visual skills are useful in natural sciences like palaeontology, providing powerful ways to document and communicate complex spatial information. Students who are interested in palaeontology will find it useful to learn how to use new digital drawing tools.

3D Dinosaur Bone Bed

As the quarry map details become updated the information is also being incorporated into the development of a 3D reconstruction of how the skeletons were oriented when buried. The quarry map provides the location of the elements and digital skeletons are posed to fit the map.

Stay tuned for more updates as the work on the quarry map continues to offer new insights.

You can now watch Episode 3 of DinoHunt Canada on YouTube.

The four part series originally aired on History Channel in January of 2015. Episode 3 “The Dawn of the Dinosaurs” focuses on the dinosaur bones and footprints found on the shores of Nova Scotia’s Bay of Fundy.

Watch the episode to see how the team from the Fundy Geological Museum work to expose the bones of 200 million year old dinosaurs, while others search for clues among the dinosaur footprints and other fossils found along the shores of the Bay of Fundy.
