The following is a brochure from the early days of Nash Dinosaurland. The text from the brochure is provided below each image.
AT STANLEY PARK
THE DINOSAURS LIVED HERE BEFORE YOU.
YES--RIGHT HERE IN PIONEER VALLEY
Over one hundred million years ago, Dinosaurs roamed the earth. In this part of the United States practically the only traces we have of their existence are some footprints that were left in mud which later hardened into stone.
Dinosaurs (the word means terrible lizard, from the Greek Deinos Sauros) varied in size with the largest reaching the weight of 30 tons and an overall length of ninety feet.
The Dinosaurs that left tracks in New England were up to thirty-six feet long and weighed up to twelve or fifteen tons. The footprints of several of these Dinosaurs are in the Stanley Park exhibit. There is a series of fifteen-inch prints, another consecutive series of twelve-inch prints and then there are smaller miscellaneous tracks. There are three seven-inch prints made by the same Dinosaur and the length of the stride indicates that the Dinosaur was running across the mud flats.
The large prints were probably made by a type of Dinosaur known as Eubrontes. The small prints were left by a type called Grallator. Both Eubontes and Grallator were bipeds.
In the same section of stone, which is 28 inches wide by 18 feet long, you will find ripple marks and evidence of fossil wood. These are indicated on the diagram. Fossil wood is indicative of vegetation during the age of the Dinosaur. Ripple marks were formed by the wind blowing over shallow water.
The series of tracks came from a quarry discovered and owned by Carlton S. Nash of South Hadley, Massachusetts. In talking of the footprints, Mr. Nash says, "The tracks were made by Dinosaurs on mud flats probably of clayish iron content texture millions of years ago. During the Ice Age, these mud flats were covered with glacial deposits from the North and slowly hardened into sandstone. Eventually from the earth's warping, volcanic action and erosion, these petrified prints were exposed. Thus the cycle was complete.
When a layer of tracks is exposed, the shale is cut with special saws, and chisels are used to split the shale and remove the track intact. Great care is taken not only to avoid breaking the tracks that are to be removed, but also to avoid damaging the tracks in layers not yet exposed. Even the toenail marks are saved. Mr. Nash has excavated over twenty-nine layers of tracks and there is no indication as to how many more layers there may be.
Two types of tracks are found. Those in Stanely Park are impressions. Mud flowing into the impressions hardened, and consequently when the layers are separated a raised track is also obtained. Both types of track are equally valued.
One track at the end of the display has been left available for visitors who would like to have their picture taken standing where the Dinosaur once stood many millions of years ago.
The quarry where these tracks were found is open to visitors. There one may see layer upon layer of prehistoric prints made long before the dawn of man. It is fascinating to watch the quarrying operation and to realize that the prints being uncovered are those of reptiles that once roamed this entire valley. At the quarry, there is preserved one large section of stone which shows the haunch and tail mark where a Dinosaur sat down to rest and there is a building made of Dinosaur prints. Single tracks or large sections containing many prints may be purchased at the quarry which is reported to be the largest and oldest of its kind.
If you would like to read a detailed description of the age of the Dinosaur, with many illustrations, you will find a very comprehensive article in LIFE magazine, September 7, 1953, Pages 62 to 69.
