With piercing eyes, a gaping mouth and bulging muscles, the
dinosaur that has been living at Polich Art Works in Rock Tavern is
an intimidating sight.
Fortunately, the beast is made of bronze.
The 7,000-pound, life-size statue of a Torosaurus latus, a
dinosaur that lived more than 65 million years ago, was cast at the
local foundry as part of a $500,000 project to create a dinosaur
statue to set in front of the Yale Peabody Museum in New Haven,
Conn.
The dinosaur will make a four-day appearance at Polich's own
Yellowbird Gallery on Front Street in Newburgh before arriving at
its final home on the Yale campus. This will be the beast's only
local appearance.
Dick Polich, founder of Polich Art Works and owner of Yellowbird
Gallery, said he was thrilled to work on the project, particularly
since he is a Yalie.
"It's wonderful," he said.
Polich Art Works, which is known for casting works by such
renowned artists as Frank Stella and Susan Wagner, was one of
several foundries around the U.S. considered for the job.
"When I first was in touch, I hadn't even realized he was a Yale
graduate," said Jane Pickering, Yale Peabody Museum deputy director.
"It was a nice coincidence that they were the best foundry in the
country for doing this sort of thing."
Group effort
Polich said about 90 percent of the foundry's 75 employees worked
on the project, casting the beast in 30 pieces before welding them
into one.
"Our goal is that no one can tell where it was put together,"
Polich said. "We are anonymous. We don't make it better, we don't
make it worse."
The life-size model is 21 feet long and measures 12 feet high to
the top of its frill, the plate-like protrusion on top of its
head.
Polich Art Works patinist Genaro Guevara used oxidizing agents
that reacted with the bronze to create the green and brown tones in
the dinosaur's skin.
"The detail on the piece itself is very amazing," he said. "It
was difficult working and trying to get it to ook like what the
artist pictured it."
Artist and Yale Peabody Museum staff member Michael Anderson
designed the creature.
"It's interesting sculpturally. It has horns like a bull, a beak
like a bird and nostrils like a rhinoceros," Anderson said of the
Torosaurus. "It's just wacky."
Anderson visited Polich Art Works Monday to oversee the final
touches on the bronze's patina. For him, the bronze casting was the
culmination of six years of work on the project.
Much of that time was spent researching how to build the dinosaur
from the inside out — bones, muscles and skin.
He then created a life-sized clay model of the beast, which was
used as the form for the bronze casting. Creating the skin in clay
alone took six months.
"This has been an unbelievable experience for me," Anderson said.
"Just incredible."
Torosaurus latus roamed the earth during the Cretaceous period
about 66 million years ago. It is part of the same group of frilled
and horned dinosaurs as the Triceratops, and was a herbivore.
The creature was named and described by Yale professor of
paleontology O.C. Marsh in 1891. Marsh also identified dinosaurs
such as the Tyrannosaurus Rex and Stegosaurus.
These more famous beasts were suggested to be the statue's
subject, but in the end, the Torosaurus won out. The project was
funded by a gift from 1956 Yale alumnus Stanford N. Phelps, his wife
Elizabeth and their grandchildren.
"It's a real Yale dinosaur," Pickering said. "It's really
appropriate to have outside of the museum."
The Torosaurus will be transported to the Yale Peabody Museum in
mid-September and set on a large piece of granite. The statue will
be covered until the dedication ceremony Oct. 22.

How to craft a giant
To make the clay model:
No Torosaurus skeleton has been found complete, so artist
Michael Anderson modeled the dinosaur's body after that of a
Triceratops because they have similar body structures.
- Anderson then used foam board to mimic the contours of the
Torosaurus' skull, which is part of the Yale Peabody Museum's
collection. The skeleton was created on a one-third scale bone for
bone.
- Anderson studied the muscles of iguanas, alligators and other
reptiles closely related to dinosaurs. He then built the muscle
structure with clay onto the recreated skeleton.
- The skin pattern was created by combining several reptile skin
patterns. The one-third scale model was not completely covered in
the patterns.
- Once the one-third scale model was complete, it was recreated at
three times the size in foam and covered in clay.
- Anderson and a team of volunteers spent five months shaping and
applying each scale for the skin.
- The model was then taken to Polich Art Works to be cast in
bronze.
To create the bronze:
- The clay model was covered in a black rubber polymer followed by
a plaster mixture to create the molds.
- Wax casts, then ceramic shell molds, are created using the
plaster molds. The Torosaurus was cast in 30 pieces.
- The plaster molds are filled with molten bronze.
- The bronze is welded together.
- Once welded, chemical agents were applied to the dinosaur to
create a green and brown patina, giving the beast its color.
The first phase of creating the dinosaur took more than two years
and required the help of more than a dozen experts, two assistants
and 20 to 25 volunteers. The bronze casting took about 10
months.
