She is a member of the Salem Land Trust and now in Uncasville. Another collec- tion was donated by Virgil M. Horn, who collected rocks and minerals while on vacations throughout the Northeast and during many trips as a troop leader with the Boy Scouts of America. After Mr. Horn passed away in 1998, his son Howard Horn, of Rocky Hill, CT, wanted the collection used for educational purposes.

Thanks to the generosity of Mr. Horn and Ms. Chester, and the assis- tance of Ken and Ali, the park now has an extensive variety of speci- mens.

Both collections include specimens that will remain in the park collec- tion for teaching and display, as well as some that will be given away to students participating in programs covering rocks and minerals of Con- necticut or Connecticut landforms. In addition, many teachers who par- ticipate in our Landforms Workshops will receive specimens for their classroom collections. Those items given away will include a Dinosaur State Park label listing the name of the specimen, where it was found, and the name of the person who collected or donated it.

Despite news reports to the contrary, available evidence continues to support the long-held view that Archaeopteryx represents the most primitive known bird, while new finds are adding significantly to our understanding of the earliest stages of bird .

The latest study, led by Gregory Erickson of Florida State University, Tallahassee, Florida, examined the histol- ogy of a juvenile Archaeopteryx. The bones were found to be slow-growing, nearly avascular, and parallel-fibered.
