7. This is the locality furnishing for the Amherst Museum the large rows of tracks of Brpnto- 

 zoum Giganteum, the largest of the Triassic birds. Across the river, in South Hadley, is an 

 excellent locality of Otozoum Moodii, so named for Pliny Moody, who was the first person in the 

 Connecticut Valley known to have observed any of the footmarks. A specimen is preserved 

 which he dug up in 1800, saying that " the tracks were made by Noah's raven." 



8. The noted locality of fossil footmarks is at Turners Falls, on a branch of the F. T. & B. 

 E. R., four miles distant. W. W. Draper was the first person to observe them, in 1835. He sug- 

 gested that they were " turkey tracks made 2,000 years ago." His impressions were communicated 

 to Col. Wilson, who called the attention of Dexter Marsh to them. Mr. Marsh showed them to 

 Dr. James Deans, who requested Prof. E. Hitchcock to investigate them scientifically. This was 

 done, and the results accumulated in the Hitchcock Ichnologlcal Museum at Amherst, where are 

 over 20,000 separate ichnites, illustrating about 160 species, all from the Connecticut Valley. 



9. This is the town where the celebrated Helderberg limestone crops out. It is believed to be 

 a remnant of a once extensive deposit, preserved accidentally from erosion, and resting upon or 

 folded beneath the Coos Quartzite.
