Sketches and changing minds: the case of Batallones

Working with digital media makes it easier for an artist to go straight for final art withouth bothering too much with preliminary sketches. After all (and compared with, say, oil painting) it is now so much simpler to make things up as you go along… But nothing equals the flexibility of the good old pencil-and-paper when it comes to quickly visualize a complex scene and turn it around in our mind.
One nice example of this was the series of sketches I made for the Batallones Miocene scene that appears in page 53 of my book “Sabertooth”. Originally created for an exhibit at the Museo Nacional de Ciencias Naturales in Madrid, the painting had to depict most of the relevant species of mammals found at the fossil site, and that is A LOT of creatures!
When you have to fit so many species in one single scene, it is almost impossible to include any violent action, but I could not resist to show the sabertooth Machairodus doing business!. So even in my earliest sketches I depicted a couple of the large sabertooths in the act of catching a rhino. One felid was on the hapless prey while the second one was approaching cautiously as the cats will do. Other rhinos were escaping towards the right margin of the frame.

Here is one of the earliest sketches. Second cat approaching, rhinos escaping to the right
version 1

The arrangement seemed to work, but in a later version I started to incorporate more of the species that I needed to include, and found a problem: having one cat approaching took too much space in the scene, so I had to find a way to concentrate all the action in a smaller space.

Here is another version, with more creatures in the frame, and the cats occupying more than their fair share of room!
version 2

It is not only a matter of the animals occupying too much room; it is also the fact that their activity reverberates and seems to ask for breathing room around them, a luxury I could not afford in this project! So I decided to show both cats engaged with the prey, one delivering the killing bite while the other added its weight to the fight.

Here is a sketch of the two cats on top of the hapless rhino
version 3

I will spare you the profusion of sketches that followed, suffice it to say that I decided to turn around the cats and rhinos scene so that they look away from us, which fits better with the direction the rest of the herd are escaping. By the way, I made the herd run to the left so that their action went into the frame rather than out, a device that keeps more “energy” within the composition.

Here is one much later version, where most of the elements are already in their definitive positions
version 4

Even with the flexibility of the digital media, there is no way I could have made all these changes as I worked on the final piece of art. But more importantly, changing elements around in an already ellaborated digital painting can be such a painful process that you often end up leaving things much as they were, just to spare yourself the agony of adding modifications. On the other hand, exploring different alternatives with lightning-quick pencil sketches is not only a much more practical way to shape your composition: it is so much more fun!

And here is the final version of the painting:

Safari “hangover”: returning from an African Eden

We are back from another amazing edition of the “Drawing the Big Cats Safari” to Botswana. In fact we have been back for more than a week, and yet the process of adapting once more to everyday life feels a bit like a diver’s decompression.
The safari experience has something primeval about it, as if we were returning to the natural state of humankind in its childhood. For days on end our senses are continously soaked with the sights, sounds and smells of nature, and our brain is suddenly doing what it was designed to do -in fact it feels happy and at home, like a puppy allowed to run in the park, or like a dolphin splashing in the waves. Each night you collapse in your tent’s bed with your mind full of images to process, and yet utterly at peace.
Such a routine is in stark contrast with our daily life back in the “civilization”, and we have to come to terms with the implications, because a trip of this sort is much more than a vacation. We have fed our mind with the kind of high-quality food that will keep our creativity fuelled for months and years to come. But we know we are transiting between contrasting worlds. Each time I experience the pristine wilderness of Africa I am reminded that countries like Botswana are preserving such natural treasures at a cost. A lot of effort and sacrifice are neccesary if our shared heritage has to endure, and ecotourism is one way we can all contribute to make it sustainable in the long term. I never tire of repeating it, a safari to the African wilderness is an experience that will improve your life. Stop just dreaming about it and start planning for it. You will not repent -and you will return!

Heading for Botswana!

Today we leave for Botswana, where we will meet a fresh group of enthusiastic artists, plus the fabulous team at Elephant Trails Safaris, and hopefully…the big cats!

Looking at our pictures from last year’s trip, like this alert leopard from Chobe Natonal Park, we think we can´t beat those encounters…but, who knows?

We will be chronicling on this second edition of “Drawing the Big Cats” upon our return, so stay tuned!

“The Cradle of Human Kind” opens at the Museo de la Evolución Humana

After the great success of the exhibition “The Cradle of Human Kind” during the months it has been open at the Museo Arqueológico Regional, it is time for it to arrive at the “Museo de la Evolución Humana” in Burgos. Besides making it available for the general public (admission is free, by the way), this will also be an excellent opportunity for all attendants to the upcoming UISPP congress to see it!

Denizens of Madrid’s Miocene Woods: The “Dog-Bears”

The so-called dog-bears, or hemicyonines were actually much closer to bears than to dogs; in fact, most specialists classify them as just a subfamily Hemicyoninae within the bear family or Ursidae, although there have been proposals to grant family status to the group, as Hemicyonidae.
But in spite of their close affinity with modern bears, these animals would have looked quite un-bear like to a modern observer, because of their body porportions and gait. One good example of this would be Hemicyon sansaniensis, a species typical of the group and widespread in the Miocene of Western Europe, including the Madrid region.
Hemicyon sansaniensis had the body mass of a small brown bear, but it differed from any bear in having a longer back and longer metapodials (foot-bones), which were straight and parallel and indicate a digitigrade posture. Such body proportions are actually more similar to those of a big cat, and it is likely that Hemicyon would stalk its prey and hunt actively, a bit a like a big cat.

But the dentition of Hemicyon was certainly not cat-like. It was more adapted to processing meat than that of “normal” bears, but it was also fit for dealing with other types of food, including vegetable matter.
Like the bear-dogs of the family Amphicyonidae, these animals are good examples of the evolution of caniform carnivorans during the Miocene, when they filled rather broad niches as hunters, scavengers and omnivores. But such niches would be compromised by the arrival of the true big cats, and especially of the sabertooths, which soon became the dominant hunters of large prey and established new rules for the Miocene large carnivore guild.

Denizens of Madrid’s Miocene woods: the Bear-Dogs

For most of the early and midlle Miocene, cat-like carnivorans had to play a subordinate role in the predator guild of Madrid’s woodlands and prairies. The dominant hunters and scavengers in those ecosystems belonged to the Caniformia (which is the “dog half” of the order Carnivora), and they included two groups known with the confusing popular names of “Bear-Dogs” and “Dog-Bears”. The “Dog-Bears” or hemicyonines, were close relatives of today’s bears, and will be discussed in a different post.
The “Bear-Dogs” or Amphicyonids, were neither dogs nor bears, but a separate family distantly related to both. Most of them had a rather unspecialized dentition with a nearly complete set of premolars and molars, resembling in some ways the dentition of dogs, and suggesting a similarly varied diet. But their skeleton was not especially dog-like in most cases, and instead it resembled a mixture between a bear and a big cat in terms of body proportions and locomotor adaptations.
One of the most common and well-known members of this family was Amphicyon major, an animal similar in size to a modern brown bear and whose remains are found in several fossil sites in Madrid. Well adapted to a life as an active hunter, scavenger and omnivore, it would keep the modest cats of the time (the largest of which was leopard-sized) easily at bay.

Here is a reconstruction of Amphicyon major in the middle Miocene environments of Casa de Campo, an area that today is covered with mediterranean bush and woodland, but which during the Aragonian was part of a savannah-like floodplain with gallery woods near water. These two individuals are disputing a carcass of Triceromeryx.

Remembering Alan Turner

Alan Turner was so much more than a collaborator to me. For two decades, he was my informal paleontology teacher, my mentor, creative partner and close friend. Together we produced several books and many scientific papers, but we also shared family vacations and flamenco evenings. Losing him over two years ago was such a shock that it actually didn’t seem real. In many ways, he is still far more real, for some of us, than his absence. We have his work, and a whole lot of great memories that feel today as fresh as ever.

To celebrate Alan’s work, Quaternary Science Reviews has now published a tribute volume including an introduction, an obituary and an impressive collection of scientific papers. Courtesy of Elsevier, for the next 50 days you can access the obituary by following this link:

Denizens of Madrid’s Miocene woods: the Mastodons

One of the most important faunal events during the early Miocene of Europe was the arrival of the first proboscideans, or elephant relatives, some 19 million years ago. Those wonderful beasts left their African home when land bridges allowed, and spread throughout Eurasia, eventually to cross the Bering bridge into North America. Wherever they arrived, they did not simply become a part of the landscape: they changed it, acting on the vegetation like a sort of biological bulldozers that contributed to the spread of grassy patches and to keep the forests at bay.

Those early proboscideans, popularly known as mastodons, were rather different from our modern elephants. Gomphotherium, the most widespread genus from the early and middle Miocene, is a good example of the classic mastodon. Short-legged and robust, it had a body mass comparable to that of an Asian elephant, but was considerably less tall at the shoulders. Like most proboscidean species of the Miocene, it had four tusks, one pair on the maxilla and another one at the end of the elongated mandible, giving the animal a bizarre (to our eyes) appearance. And its cheek teeth had a more simple pattern, adapted to process softer vegetation than in the case of true elephants, mostly leaves and twigs -no grass.

Here is a life reconstruction of Gomphotherium in its environment

Ever since then and until the end of the Pleistocene ( a “mere” 10,000 years ago), the landscapes of Eurasia and North America were never without proboscideans of one kind or another, often with more than one species coexisting at the same time. For that reason, African and Indian wilderness offer important references to imagine how the vegetation of prehistoric Eurasia and North America would have been influenced by the action of such phenomenal creatures.

Reconstructing sabertooths… How is it done?

In “Sabertooth” I have included a few notes about the reconstruction methods that I used for preparing the illustrations of the book. But there was only so much I could pack into a section of a chapter of a book which already covers such a range of sabertooth-related topics.

So if you are REALLY curious about the whole process of reconstruction, from fossil site to finished illustration, I suggest that you download the video “Bringing the Sabertooths Back to Life”.
