Louis Antoine de Bougainville (November 12, 1729 – August 31, 1811) was a French scholar, military officer, and explorer. He was a brilliant mathematician, gained fame for himself fighting in the French and Indian War, he became the first Frenchman to circumnavigate the globe, and he conducted an extensive exploration of the South Pacific. Bougainville Island, where a ferocious battle took place during World War II, is named after him.
This is a drawing as he would have looked in his 20s during his service in the French and Indian War as a captain in the French Army and as the aide-de-camp to Gen. Louis Joseph, Marquis de Montcalm. Made using a combination of No.2 pencil, colored pencils, and markers. The portrait that you see is based upon several existing portraits of him from later in life (none of them being full portraits), especially his distinctive blue coat with the gold Celtic-style braiding.

Chasmosaurus was a common genus of ceratopsian dinosaur found in North America, especially Alberta, Canada circa 75 MYA. This creature is so recognizable due to its rectangle-shaped frill that it has given its name to a whole slew of other ceratopsians that are related to it – the “chasmosaurine” ceratopsians.
Made with regular no. 2 pencil on plain white printing paper. The actual drawing of the creature from the tip of the beak to the tip of the tail measures just a smidge over seven inches. Scanned at 600DPI to show as much of the detail as possible.
Keep your pencils sharp, everybody.
I just now hashed out a sketch of the famous Early Permian pelycosaur Dimetrodon – specifically, this is Dimetrodon grandis, one of the largest North American species, measuring at 10 feet long. There’s been a bit of buzz about this wide-ranging genus in recent weeks due to a new species discovered in Canada.

Today marks the 100th anniversary one of the most important dates in modern European history. On the Monday after Easter in 1916, a group of young heavily-armed men dressed in military uniforms stood outside the front doors of the General Post Office in central Dublin. There, one of their number, a young poet named Podraigh Pearse (the name is often Anglicized as Patrick Pearse), read a document called “The Proclamation of the Irish Republic”. In front of a curious and ever-growing crowd, he called for full and complete independence from British rule, which had existed in Ireland since the Middle Ages. Then, taking up defensive positions within the post office and elsewhere in the city, Pearse and his fellow rebels awaited the inevitable British military response. What happened next has become a core part of Irish history and cultural legend.
In its immediate sense, the Easter Rising was a failure – all of the defensive positions were taken by British forces and the ringleaders were executed. However, it marked a sea change in Irish nationalism. Previous Irish rebellions had been essentially one-offs, flaring up and then being supressed, with many decades of down-time taking place between each independence attempt. In one circumstance, a whole century went by without any hostilities. However, after 1916, many Irish now made a concerted effort to drive the British out of Ireland for good. This resulted in the rebellion which finally culminated in Irish independence in 1922. I’m certain that the 100th anniversary of Irish independence in 2022 will result in massive celebrations seen throughout the country.
Since the Easter Rising of 1916 is clearly seen by many as the initial spark that led to Ireland becoming free after nearly 800 years of British rule, the 100th anniversary of this event is being marked with great celebration within Ireland itself and amongst Irish populations elsewhere. PBS has regularly been airing programs about this event, a play was created commemorating it, and Irish and British news media have been crackling with item pieces on this event and how it has effected modern Anglo-Irish politics. Both the Easter Rising and its anniversary are important historical and cultural milestones, especially for the people of the British Isles, and I’m happy to see that there has been a lot of conscious media attention on it.
I wish that I could say that there was more, especially in the United States, where the mainstream media don’t seem all that interested in such things. I remember that the 150th anniversary of the Battle of Gettysburg in 2013 received minimal media attention. The 150th anniversary of the end of the Civil War in 2015 received hardly any attention at all, and the 250th anniversary of the passing of the Stamp Act of 1765, also in 2015, which many people see as one of the defining moments in the move towards American independence from Britain, received absolutely NO RECOGNITION WHATSOEVER! To a historian like myself, this is nothing short of deliberate historical and cultural extermination, a detestable process in which the hallmarks of people’s history are ignored or discarded in favor of other things which we are brainwashed into thinking are more important. The reason for this is disturbingly simple – nobody in the US really gives a damn about such things anymore. In today’s fast-paced tech-obsessed reality TV-obsessed society, things like history are seen as boring and irrelevant. I once worked with someone who hated history because, in her words, “it’s of no use to me now”. I can’t stand it when people have this mindset of “if it doesn’t benefit me personally, I don’t need it”. In a way, I can understand this way of thinking. Really, are all of those names and dates really important to your normal day-to-day affairs? Probably not. However, as the old saying goes, those who forget history are doomed to repeat it. When people lose sight of their own cultural heritage, it makes it all the easier for them to be manipulated and molded by those who are in power, either at home or abroad. I’ve been seeing this for years with the emergence of so-called “sheeple”.
In Europe, including Britain and Ireland, history is a living breathing thing. It’s a palatable thing in the air and earth. In America, I don’t see this. I see people who are only concerned with the present and the future, and give little to no thought about the past. No wonder that college and university history programs are dying all across this country. No wonder that having a history degree is considered useless when looking for a job. What will happen in 2025 when America has the 250th anniversary of the beginning of the Revolutionary War? Or in 2041 with the 100th anniversary of the bombing of Pearl Harbor? Sure, there will probably be a handful of quick news items on it, and maybe a few special edition magazines seen on news stands, but aside from that, I dare say that these upcoming important anniversaries will be acknowledged by a collective shrug. People in the US will take a quick note of this, say something like “Oh, that’s interesting”, and then move on to what they were doing before and give no thought to it for the rest of the day.
For me, this is sad. I place great value on history and historical memory. I’m sure a lot of other people in the United States do too, but for the most part, I don’t see it. I see people who are losing sight of their historical heritage more and more with every passing year. Is it any wonder why we’ve been seeing platitude-spouting demagogues taking center stage in American politics? When history is forgotten, history can get twisted around to suit other people’s ends. American historical memory is being constantly re-written so that people here imagine that things played out differently than they actually did. Incorrect facts are being constantly touted as cold hard truth. Historical characters are cast in exclusive good/bad, black/white relationships to each other with no gray area in between. TV channels, such as “The History Channel” of all things, have replaced informative programming with, well let’s be frank, bullshit. The History Channel, which by the way is no longer called that, is now dominated with programs on aliens, rednecks, Alaska, the Bible, doomsday, and Nostra-fucking-damus.
I look at all of this for what it is – the gradual eroding of history, the altering of historical memory, and by extension the manipulation of culture. In Europe, history is alive and well. In America, it’s dying.
This is an idea that I’ve had knocking around in my head for a while. A recent post by fellow paleo-blogger Chase (who has a special interest in eastern North American Mesozoic life) on Dryptosaurus has spurred me to action in terms of writing a short article as well as doing some much delayed artwork.
For those of you who are too lazy to read Chase’s excellent article about this animal, Dryptosaurus was a medium-sized theropod dinosaur, approximately 20-25 feet long which lived in eastern North America during the late Cretaceous Period. Unfortunately, our total knowledge of this dinosaur is known from only a few fragmentary remains, including a hand claw that seems way too big in proportion with the rest of this animal’s body.
For as far back as I can remember, Dryptosaurus was classified as a tyrannosaur. But recently, I have my doubts about this classification. Even very primitive tyrannosaurs such as Guanlong and Proceratosaurus don’t have some of the anatomical features that Dryptosaurus appears to possess.
My curiosity centered around that claw. It didn’t look like a tyrannosaur claw – to me, it looked more like an allosaur claw. An unusually large hand claw also reminded me of another animal – Megaraptor, from South America. Originally, this was thought to be a gigantic dromaeosaur, but then it was hypothesized to be more closely related to the allosauroids, like Neovenator, Giganotosaurus, and Carcharodontosaurus. The allosaur-like claw would make this classification a good fit. Then I saw a picture of the skeletal remains of Australovenator, a megaraptorid that was discovered in (you guessed it) Australia. I immediately noticed similarities in the hand and body structure between Australovenator and Dryptosaurus.
- Massive thumb claws in comparison with the other finger claws.
- Short muscular arms and huge hands
- Slender lower jaws with small closely-packed hook-shaped teeth.
What I find really interesting is that in 2012, a hypothesis was put forward by Fernando Novas and other paleontologists that the megaraptorids might actually be extremely primitive members of the tyrannosaur family. In 2014, fragments from a juvenile Megaraptor were discovered, including part of the upper jaw. The structure of the juvenile Megaraptor’s maxilla was very similar to the structure of the dentary from Australovenator. That year, Juan Porfiri re-iterated Novas’ hypothesis that the megaraptorids might be primitive tyrannosaurs.
So, with all of that being said, I hypothesize that Dryptosaurus was a member of Megaraptora, which would make it the first of its kind found within North America.
How did Dryptosaurus feed? The large hook-shaped claws and the small hook-shaped closely-packed teeth seem to indicate that Dryptosaurus and other megaraptorids were fish-eaters. The fossils of Dryptosaurus were discovered in the New Egypt Formation and the Navesink Formation, the later of which is known for both dinosaur fossils as well as fossilized shells. Also, Australovenator was found in deposits that indicate a swampy still wetlands environment, full of bivalves, fish, and turtles. The fact that this megaraptorid was found in a water-rich environment full of aquatic life leads me to suspect that Dryptosaurus might have had a similar lifestyle.
To conclude this short article, I have a drawing of the enigmatic Dryptosaurus portrayed as a megaraptorid rather than as a typical often-illustrated tyrannosaurid. Who knows – maybe my less-than-scholarly idea about Dryptosaurus being a fish-eating megaraptorid will prove out to be right. Only time and the discovery of more specimens will tell.
Keep your pencils (and minds) sharp, everybody.
Anzu was a caenagnathid from the Hell Creek Formation. I wrote of its discovery and naming in an earlier post that you can read here. The caenagnathids were a primitive group of oviraptorosaurs, the “egg thief” dinosaurs. Anzu is so far the largest species from this group found in North America, measuring 10-13 feet long from nose-tip to tail-tip, and it was also one of the last of its kind.
In terms of this picture, the chicken-like wattles are purely conjecture on my part, as are the types of feathers and color patterns.
Torvosaurus tanneri (“Nathan E. Tanner’s savage lizard”) was one of the largest theropod dinosaurs in the Morrison Formation. It measured 35 feet long, the same size as Allosaurus. However, Torvosaurus came from a more primitive line of theropods, the megalosaurs. As such, it retained some more primitive features compared to more advanced theropods living at that time like Allosaurus, and was probably less intelligent than Allosaurus (although not by much, apparently, since Allosaurus wasn’t exactly the brightest bulb either, according to studies of Allosaurus’ brain).
Torvosaurus and Allosaurus may have lived in the same location at the same time, but Allosaurus was clearly the most numerous theropod in the Morrison Formation. Very few remains of its competitor have been found. The first fossils of this animal were discovered in Colorado in 1971, and the species was officially named and described in 1979. Another species, T. gurneyi, was found in Portugal’s Lourinhã Formation, also dated to the late Jurassic. Although known from incomplete remains, it’s evident that the European species has a more boxy rectangular skull than its North American counterpart.
Torvosaurus and Allosaurus had the same length, but they possessed different physical proportions. These anatomical differences no doubt drove these two species to develop different hunting styles. It seems that Torvosaurus was a Jurassic analog for a tyrannosaur, since it had an unusually large head and unusually small arms in proportion to its body. Its body was long and shallow, whereas the body of Allosaurus was short and deep – good for a large heart and lungs, indicating an active lifestyle. Torvosaurus’ neck was short and muscular, while Allosaurus’ neck was longer and more sinuous. Torvosaurus had short arms and small hands (but unusually large thumb claws), while Allosaurus had longer arms, huge hands, and absolutely huge claws – obviously used for grabbing and ripping things. Torvosaurus seems to be rather front heavy (good for physically slamming it’s jaws onto prey) while the weight on Allosaurus appears to be more evenly distributed. Allosaurus also had an unusually long tail in proportion with its body – a definite feature of an agile runner. Therefore, it seems that Torvosaurus was primarily a short-distance chase ambush hunter who relied upon its jaws to do most of the work. By contrast, Allosaurus was a very active energetic predator who was capable of impressive speed and quick turns.
This drawing took a long time, as you can assume from its high amount of detail. Every individual scale was drawn one by one. To give you a better appreciation of the time to draw this, in real life this drawing frome nose-tip to tail-tip is only 21 inches long – 1/20 scale, as most of my prehistoric drawings are. Medium was No. 2 pencil on copy paper, along with some touch-up on my computer to fix the places where the two pieces of paper were joined together.
Keep your pencils sharp, everybody.
