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. Theses 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?
In 2003 I was illustrating animals for Grzimek’s Animal Life Encyclopedia; while doing research for the chapter on hydrozoans (relatives of jellyfish), I learned that one of the species I was to illustrate was named after Frank Zappa. As it happened, the author of the Hydrozoa chapter was the same man who’d described and named that species. Italian scientist Ferdinando Boero (who enthusiastically provided me with guidance for the illustrations) had named one of these animals with the hopes that he’d be able to meet the musician. Of his plan to use taxonomy to meet his hero, Boero said:
“My strategy was a simple one:
that fauna was (and is) not well known;
I would find some new species for sure;
once I had found them I would have to give them a name;
I would dedicate one of them to FZ;
I would tell him about it;
He would invite me for a visit.”
Here is my painting of the medusa stage of Phialella zappai:

Last weekend I visited the McMichael Collection with the Southern Ontario Nature and Science Illustrators to see the exhibit “Vanishing Ice.” As described in the promotional material, this exhibit “…offers a glimpse into the rich cultural legacy of the planet’s frozen frontiers. International in scope, it traces the impact of glaciers, icebergs, and fields of ice on artists’ imaginations. The exhibition explores connections between generations of artists who have adopted different styles, media, and approaches to interpret the magical light and fantastic shapes of ice.” Occasionally throughout the exhibit, a quote related to the subject was emblazoned on the gallery wall. One such quote caught our eye. It’s from a 1937 letter to Admiral Richard Byrd written by David Abbey Paige, who was the official artist on Admiral Byrd’s second expedition to Antarctica:
I believe that after the heroic part of the expedition has been forgotten, these colour records which I have will long be remembered by the future generations. I say this as a student of history: art and science always are more successful when they are joined together, because without graphic illustrations of its results, science is less comprehensive and sometimes very dry. All through the ages, the civilized world has left its best results graphically whether in print or in pictorial form.
One of my favorite artists, Caspar David Friedrich, was represented in this exhibit with his piece “The Sea of Ice” or “Wreck of the Hope” though it seemed a rather dull reproduction of the original painting:
The piece that made the biggest impression on me was a large painting of a beautifully rendered block of ice with some penguins on it by Alexis Rockman. See it in this slideshow of the artist’s work (#5).
This piece by Spencer Tunick prompted much discussion with others in my group. Six hundred naked people lying down on a glacier! I hope it didn’t take too long for the photographer to direct that shot….
