Scientists and artists have reconstructed the look of Sri Lanka's ancient giants

These are the ancient straight-bodied elephant Palaeoloxodon namadicus sinhaleyus and the rhinoceros, historically called Rhinoceros sinhaleyus. Both are associated with fossil finds from the Sabaragamuwa Basin in south-west Sri Lanka. The work is published in the journal Palaeontologia Electronica.

The authors emphasise: these are the first scientifically based photorealistic 3D reconstructions of these animals. In addition, they are the first serious visual update of their appearance since 1955.

Details

Paleoart is art that shows extinct animals as they might have looked when they were alive. But a good reconstruction is not done "for beauty." An artist cannot simply add a spectacular pose, mane or colouring to an animal unless there is a reason to do so.

In this work, animator and researcher Jason Kennedy of Auckland University of Technology, along with palaeontologist Aravinda Ravibhanu Sumanaratna, used a 3D animation approach. They relied on fossil data, comparisons with modern related animals and digital modelling. AUT describes the approach as creating palaeoart "in the spirit of films like Ice Age, but backed by science".

The researchers reconstructed the appearance of two animals. The first is an ancient straight-mobile elephant, a member of a group that included some of the largest land mammals. The second is an extinct rhinoceros from Sri Lanka, known from Quaternary fossil records.

The main goal was not only to show what these animals might have looked like, but also to make the process itself transparent. The authors explained where they had direct data and where they had to draw cautious conclusions. For example, bones can suggest body size, proportions and shape, but soft tissues, behaviour and colouration often require comparison with modern animals.

Later, Kennedy plans to create full 3D animations of these species as well. These will show not only the appearance, but also the posture, movement and possible behaviour of the animals. Such materials can be used in museums, education and science communication.

Why it's important

It is often through images that extinct animals become known to a wider audience. If the picture is inaccurate, the viewer remembers the erroneous image. Therefore, palaeoart influences the way people represent the past as much as museum exhibits and scientific texts.

The authors of the paper believe that palaeoart should be more verifiable. In other words, it is important not only to show the finished reconstruction, but also to explain why the animal is depicted in this way. This approach makes the images closer to a scientific work, not just an illustration.

For Sri Lanka, this is particularly important. The island's palaeontological heritage is less well known than, for example, the dinosaurs of North America or the mammoths of Eurasia. The new 3D reconstructions help show that Sri Lanka also had its own megafauna - large animals that once shaped the island's ancient ecosystems.

Background

Quaternary megafauna are large animals that lived in the relatively recent geological past. It included mammoths, giant sloths, ancient elephants, rhinoceroses and other large mammals in different regions of the world.

Sri Lanka too had such animals. The fossils from Sabaragamuwa help us understand what the nature of the island was like in the past and what large species lived there. But there have been very few visual reconstructions of these animals, and older images have long been in need of updating.

The new work offers a model of collaboration between a palaeontologist and a palaeohistorian. This is important because future reconstructions of extinct animals may become more clear, honest and scientifically sound: the viewer will see not only the result, but also the logic behind it.
