My six-foot-by-four-foot illustration of three different Silurian environments in Southern Ontario is now on display at the Giant’s Rib Discovery Centre in the Dundas Valley Conservation Area. The Centre is open on weekends from 10 AM to 3 PM.
From left to right, I’ve illustrated a muddy bottom community (the Rochester Shale), a reef (the Guelph Formation) and near-shore lagoon (the Williamsville Formation). Included are trilobites, eurypterids, cephalopods, megalodont bivalves, gastropods, cystoids, crinoids, a brittle star, brachiopods, bryozoans, tabulate and rugose corals, stromatoporoids, stromatolites, and algae. See the names of all 43 different creatures here.
These ancient seas existed in the Silurian period of Earth’s history, near what we now call the Niagara Escarpment. Find out more about the ancient seas and the fossils I’ve illustrated here.
This graphite and digital color illustration is the product of some pretty intense research, and I’m extremely grateful for guidance from paleontologists Carlton Brett, Frank Brunton, and Matthew Vrazo. Some valuable reference photos also came from fossil collector Paul Chinnici, who along with Kent Smith authored a just-released book about the Rochester Shale fossils. This beautiful new book also includes a detailed chapter on the stratigraphy and paleoenvironments by Carlton Brett, illustrated with the Rochester Shale portion of my illustration above. The book is available here. I write more about the book and describe my visit to the Caleb Quarry (Rochester Shale) in an earlier post.
All are invited to the Grand Reopening of the Giant’s Rib Discovery Centre on October 17, 2015. The opening will coincide with a reception for an exhibit of science and nature illustration by the Southern Ontario Nature and Science Illustrators. I’ll post details when I have them; the agenda is not yet settled.
Last year I visited a local seafood store and brought home this live lobster:
The Royal Canadian Mint had invited me to submit a coin design showing a Canadian lobster, and I needed a specimen to draw. Having never handled a live lobster before and unsure of what to expect, I first put her in my empty bathtub to take some photos.
I needn’t have been so cautious! Since air was not her natural environment she barely moved at all. After a number of photos from all angles I concluded that I needed to manipulate her appendages and body position to achieve a pose that would work on a 13.92 mm diameter coin.
So, I put her in the freezer. As far as I could determine, this was the most humane way to kill her. Once frozen and then slightly thawed, I could pose her in a variety of ways and view her from different angles in order to determine the best composition for a small circular canvas. To be sure I was positioning the lobster in a natural stance, I viewed photos of live lobsters underwater. My specimen curled up her abdomen while in the freezer, and I never managed to uncurl it; fortunately I had taken some good reference photos of her relaxed abdomen while she was alive.
Here she is, fresh out of the freezer after having been frozen, then thawed and manipulated and propped, then re-frozen:
As she thawed, she got a bit frosty:
It’s always a pleasure to have a specimen to draw from. Very often, that’s not an option, such as when I draw polar bears or whales. Despite my distaste for seafood, I had intended to eat her so as to avoid wasting her life. However, after a number of freezing and thawing cycles I decided it wouldn’t be prudent to consume her. I hope that having her portrait engraved on 7,500 pure gold coins is a good enough legacy:
I recently had an opportunity to visit the Ramsay Wright Zoological Laboratory on the campus of the University of Toronto. The lab houses an impressive collection of zoological specimens and I was able examine them at leisure. This event was a sketching opportunity with the Southern Ontario Nature and Science Illustrators, so at some point I did stop peering into specimen jars to sit down and draw. Perhaps because I don’t live near a marine coastline, I rarely see echinoderm specimens in local collections; that’s one reason I chose to draw these sea urchin spines:
I really like echinoderms (as I’ve mentioned before), and the surprising diversity of shapes, sizes, and colors of these spines only reinforced my interest in the phylum. Subtle shades of brown, purple, gray, and orange combined with a texture and weight like fine porcelain gave these subjects an irresistible appeal. Unfortunately I didn’t have my gouache paint with me, so I did my best to capture their character with graphite.
The loose spines were in a lidless box that also contained the urchin’s test with some spines still attached. Judging from the other labeled specimens nearby, it was probably collected many many years ago. Unfortunately this echinoid was not accompanied by any collection data; I don’t know the species or locality. However, it was the only sea urchin of its kind in the box, so I believe all of the spines came from one individual.
The Threespine Stickleback, Gasterosteus aculeatus, inhabits northern coastal streams in North America along both the Atlantic and Pacific Oceans. Because the fish is so variable, some taxonomists have suggested that it comprises more than fifty species. Some years ago I wrote a poem about it. Here’s the limerick, along with my illustration:
The Threespine Stickleback
This stickleback’s armor is nifty;
Compared to the Ninespine it’s thrifty.
While three spines might seem
A taxonomist’s dream,
This species might really be fifty.
As I began to do research for my recent illustration showing Silurian environments of Ontario (see previous post), I soon came across the excellent website Primitive Worlds – a site that shows many exquisitely-preserved Rochester Shale fossils from a private quarry near Middleport, NY. I corresponded with a couple of the quarry collectors who shared more photos with me, and I in turn licensed part of my illustration for the new book the collectors put together about their Rochester Shale fossils.
This collaboration led to an opportunity for me to visit the quarry, a short road trip I made this past weekend.
The quarry is in an idyllic location for fossil collecting; it’s surrounded by trees and is set back from the road so (when the heavy equipment and rock saws aren’t operating) it’s quite peaceful. The group of collectors who use the quarry have established a relationship with the property owner; the quarry is not open to the public. I felt fortunate to have been invited there.
As you can see from the photos, there is water on the ground and the sky is gray; I chose the coldest, rainiest, day of May to schedule my visit! Normally, I welcome cloud cover and cool weather if I’m going to spend the day crawling around a quarry collecting fossils, however, the constant rain combined with the unseasonably low temperature made things pretty muddy and uncomfortable. Because of the weather, I didn’t do nearly as much collecting as I would have liked, but I still enjoyed the experience and I didn’t come away empty-handed.
Here are a few of my finds. These are common fossils from the quarry; nothing rare or especially remarkable. It’s about what I’d expect for an hour or two of surface collecting in an unfamiliar place.
My photographs of the fossils are nowhere near as good as the photos Paul Chinnici carefully created for the aforementioned book. Paul and Kent Smith, the other author of The Silurian Experience, kindly braved the chilly drizzly day to show me the quarry. Over the years, Paul, Kent, and the other Caleb Quarry collectors have amassed a hard-won knowledge of when, where, and how to extract the various fossils in the most effective ways; it was interesting to hear about their methods.
Here we are:
The book The Silurian Experience is a real labor of love and would appeal to paleontologists as well as collectors. It’s available in hard cover or spiral bound format here. Not only does it contain many high quality photos of the quarry’s fossil fauna, it also includes a chapter written by paleontologist Carlton Brett about the stratigraphy and paleoenvironment of the Rochester Shale. Dr. Brett has an incredible breadth and depth of knowledge on the subject, as well as on other formations of the Niagara Escarpment; he gave me invaluable assistance as I prepared the illustration of Silurian environments. I’ll say more about the illustration in a future post.
May 25 EDIT: Please note, this Grand Reopening is CANCELLED and will be rescheduled for a different date. I’ll post details when I know them.
On June 6, the Giant’s Rib Discovery Centre in Dundas, Ontario will have an event to celebrate two milestone anniversaries and to showcase its recent redesign, including the addition of a mural that I’ve been working on for the last four months. The large illustration shows three different Silurian environments of Southern Ontario: A muddy bottom community (The Rochester Shale), a reef (The Guelph Formation) and near-shore lagoon (The Williamsville Formation). Here are a few bits of the mural as a preview:
All are invited to attend the June 6 Grand Re-Opening. Details are here.
The Rochester Shale portion of the mural also appears in the soon-to-be-released book The Silurian Experience by Paul Chinnici and Kent Smith, with a chapter by Carlton Brett. Details and ordering information may be found here. Paid pre-orders are discounted $10.
Today I came across this article showing lovely photographs of 15 different animals that have been named after food. The fried-egg jellyfish is spectacular! I also think the pineapple fish is wonderful. The garlic bread sea cucumber seems a bit of a stretch, though. :)
It reminded me of my mental list of fishes that are named after mammals: catfish, dogfish, redhorse, sheepshead, lion fish, hogsucker, sea horse, zebra danio. Some of these I’ve illustrated, including this redhorse and this seahorse:
Then it occurred to me that somewhere on the internet, surely someone has posted a more comprehensive list. I immediately found this Wikipedia page listing not only fishes that are named after mammals, but fishes that are named after reptiles, amphibians, birds, mythical animals, invertebrates, other fishes, and more! It does not include a list of fishes that are named after plants or foods; but I bet there are others besides the aforementioned pineapple fish.
I decided to search for a list of mammals named after fishes….but no luck. Anyone know of any?
