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.

Life reconstruction of Hemicyon sansaniensis

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”.

Big Cat Warriors: Introducing the lions of Savuti

I have been fascinated by Savuti and its lions ever since I first watched that masterly film by Dereck and Beverly Joubert, “Eternal Enemies”. Since then I have been privileged to visit Savuti 3 times, and in each occasion that beautiful, haunting place has shown me a totally different face.

The Savuti “Marsh” is the relic of a large inland lake, which dried long ago, and is now fed by the erratic Savuti channel. It occupies a large area in the west of the Chobe National Park, Botswana. Our first visit was in 1993, when the Savuti channel had been dry for several years. We were in the middle of the dry season and the place looked like the ideal location for a crepuscular Western film. In the bone-dry plain that once was a marsh, we came across the legendary Maome pride, which showed us its most powerful side -that of the giant killers. They had hunted a huge male giraffe and were taking turns to get inside the prey’s ribcage to eat their fill. Then they would come out and walk towards the shade of a nearby acacia, passing just a few meters from us. One of them actually was too full to continue and lay down to rest in the shadow of our vehicle! That was what I call an introduction to Savuti, to wild lions and to wild Africa!

When one of the lionesses leaves the kill and passes a few meters from us, we observe the wounds in her hind leg, probably inflicted during the hunt

In 1995 we returned to Savuti. It was the end of the rainy season, and the marsh, alhough waterless, was much greener than the previous time. And the lions showed us a different facet too: their family life. Lionesses and cubs relaxed and played among the greenery, in a scene that was as idillic as the previous time had been stark.

But we were as yet to meet the legendary male lions of Savuti. These warriors of the feline world spend most of their time on patrol, and checking nearby prides, moving through an enormous extension of land and occasionally leaving the protected areas -only to be shot by reckless human hunters. At least that was the case until Botswana finally took the bold step of banning trophy hunting altogether.

Then last year we finally returned to Savuti, to find the place totally unrecognizable. Subtle tectonic movements had caused the Savuti channel to flow once more, and the marsh was again true to its name, teeming with water birds and attracting herbivores from miles around in the middle of the dry season. And then, at long last, we came across the feline lords of Savuti. A wild animal does not exist in isolation, and it is impossible to separate the Savuti cats from the stark beauty of the place where they live. These lion prides have survived here through the harshest environmental changes, and now they are adapting to a wet Savuti Marsh once again. We humans go there when we can to marvel at their power, but the lions are tightly tied to that merciless patch of land.
I can hardly wait to get back to Savuti and see those incredible felines again!

Smilodon chase, or changing our minds while we sketch.

The chase scene with Smilodon and Macrauchenia which appears at the top of this blog’s home page was first conceived as an African scene with the sabertooth Lokotunjailurus in pursuit of some Hipparion horses. Years later I needed to do an illustration of a South American Smilodon hunting (for the “National Geographic book of Prehistoric Mammals”), and I picked up one of the many preliminary sketches I had done for that old scene, and simply replaced Lokotunjailurus for Smilodon and Hipparion for Equus (Amerhippus).

Here is one early sketch for the South American scene, with Smilodon and Equus

Then I realized that the 2 species shown were North American invaders, would it not be better to include a native South American ungulate in the scene? So I drew Macrauchenia as the target, instead of the horse.

In this next version, Macrauchenia is the sabertooths’ intended victim

This illustration was intended to fill a double page spread in the book, so the next thing I did was to add more elements in order to fill a horizontal format.

In this third version, a mixed herd of Macrauchenia and horses flees from the surprise attack of the sabertooths

But at one point I realized that in this composition the book’s gutter would cut the adult Macrauchenia in half, and also the animals would look a bit small in the scene. So I deleted the horses, replaced the right-hand horse for a Macrauchenia, zoomed-in on the scene to bring the animals closer, and shifted the center of the scene slightly to the left so that the gutter spared the main Macrauchenia.

Here is the next version, a zoomed-in composition, minus the horses

What I did not anticipate was the designer’s decision to include a black band with vertical text on the right-hand margin of the spread. This pushed the whole scene to the left and now it was one of the leaping sabertooths which was nearly severed by the gutter! Back then I was still painting in oils so I could not change the scene. If I had painted it digitally by layers it would have been a relatively simple matter of pushing elements to one or the other side…

And here is the finished illustration!

This, by the way, was one of my last oil paintings. Creating so many complex scenes for this book, and doing it all in record time, left me utterly exhausted, and I felt it might be the right time to explore the possibilities of the digital media. And so it was!
