Why Moving a Giant Dinosaur Fossil Can Crack a Road

For paleontologists who find the fossilized remains of giant dinosaurs, the most problematic part of the process may not be the digging up of the fossil itself but rather its transportation to a laboratory setting. As one instance that occurred in Patagonia demonstrated, even the movement of a titanosaur's fossil might result in a road being destroyed by the vehicle that carries the fossil.

It is not surprising that such an occurrence would remind us of a basic truth that scientists frequently encounter, which is the fact that these creatures were huge when they were alive, and their fossils continue to be bulky.
Titanosaurs were some of the largest land creatures that ever existed, and they pose difficulties in their handling after their excavation.

Why are titanosaurs so difficult to move

The titanosaurs were not a single kind of dinosaur; rather, they were a family of long-necked dinosaurs that existed during the Late Cretaceous era. The article by Taylor et al. titled "The Evolution of Body Size of Titanosauriforms: An Incomplete Tale" in PubMed states that "the clade produced many of the biggest land animals ever known." Their huge size makes it difficult for fossil recovery.

When fossils are unearthed, they are not individually packed for transportation. Instead, they are protected in plaster jackets together with the rocks surrounding them. Although this ensures that the fossil is well-preserved, it adds a lot of weight to it. It means that one fossil alone could be much heavier than what the transporting system was meant to carry.

The role of physics in fossil transport

The issue of the difficulty of transporting large fossils is not simply because of their weight but also due to the way this weight is distributed on the vehicle and the road network. For example, when putting a large fossil jacket onto a truck, the pressure exerted by the object will be applied on certain parts of the vehicle; the tires, axles, or the road itself may be subject to damage from the transportation of such fossils.

Past documents have proven this case. The historical documentation of the U.S. National Park Service indicates that there has always been an issue with fossil transport, as this involves both the preservation of the fossils and the safety of the roads used for their transportation. According to the service's documentation of the Uintah Railway, this issue was evident in past cases of fossil transport.

Patagonia and its history of giant finds

The region of Patagonia has proven to be crucial in unearthing fossils belonging to the largest dinosaurs. In yet another study published in PubMed, researchers found that titanosaurs are among the largest creatures to roam the earth, and many of the specimens have been discovered in Argentina. This has led the author to conclude that "some of the most gigantic forms were recovered from Cretaceous deposits of Argentina."

As such, researchers are not strangers to large-scale excavations within the region. Nonetheless, every excavation requires a different approach, depending on the dimensions and the terrain surrounding the fossilized remains.

What a cracked road really shows

The impact that was made on the roads during the movement of the titanosaur fossil is not only a unique detail. This example demonstrates how much weight there was and the limitations that are imposed on some routes for transportation purposes. Usually, in the case of road construction in remote areas, the road is created for ordinary traffic, not for several tons of weight.
In most cases, such an event cannot be related to any bad organization; rather, it is a clear example of the difference between prehistoric size and modern engineering systems.

Why is transport as important as excavation

However, even once the fossilized remains have been unearthed, the process is far from over since transporting them can be almost as complicated and labor-intensive as digging itself. It could take months of preparation to get a fossil ready for transportation, and a simple error made in the process will nullify years of work done.

It is important to point out the common opinion that the paleontologist should think of himself as an engineer and estimate all load capacities, road strengths, and choose the safest way of transport. All this is further emphasized by the National Park Service's history.

A modern reminder of ancient scale

Patagonia proves that the size of prehistoric creatures is a factor that influences modern researchers. The titanosaurs were creatures designed with regard to size that even modern people find difficult to deal with. Despite millions of years having passed since these species ceased to exist, their remains may break modern machinery, cause road damage, and require careful planning for extraction.

Thus, Patagonia demonstrates once again that paleontology is not just about research; it often implies dealing with physical realities as well. For paleontologists to be able to examine prehistoric fossils, they should be brought to laboratories or museums, and this operation itself often presents some difficulties to be overcome first. This particular case proved that even when the fossil was transported successfully, the road was damaged in the process.
