You added in a comment that you think the story "Hermes to the Ages" by Frederick D. Gottfried was in the anthology you're looking for. As far as the ISFDB knows, that story has appeared in only one anthology of dinosaur stories: The Science Fictional Dinosaur, edited by Robert Silverberg, Charles G. Waugh, and Martin H. Greenberg:
The poem you described was identified in my previous answer as "Reward of Virtue" by L. Sprague de Camp, published in The Magazine of Fantasy and Science Fiction, September 1970, available at the Internet Archive. Unfortunately, The Science Fictional Dinosaur does not contain that poem or any other. (So says the ISFDB, and I checked my own copy.) Here is a possible explanation: You said you read the book in a college library. Librarians are notorious for pasting things in books. Maybe a rogue librarian pasted a copy of de Camp's poem "Reward of Virtue" onto a blank page in the front of a copy of The Science Fictional Dinosaur?
You can check the contents of The Science Fictional Dinosaur at the ISFDB and see if the titles look familiar. Some of the stories are available online:
