Hello Charles Thank You for the information. I thought the mention of the female masterdons holding their babies up was so sad. Now if dinosaurs died out in the Cretaceous c 65million years ago.... The footprints at Glen Rose were mistakely thought to be those of humans. The 16 inch footprints were misidentified in the 1930's Alot of work has been done since and I think the earliest pre-hominid ones are from ones identified by Mary leakey 3.5 million years ago at Laetolil, 25 miles southwest of Olduvai Gorge in Tanzania. I also think the earliest 'primitive' human prints are from c350,000 years ago (according to New Scientist 2004) found in remains of volcanic ash in Italy. Anyway less of this as I'm off list sujbect here Thank you again Gill ----- Original Message ----- From: "Charles A Wyly" <wyly1@juno.com> To: <gilliandavies@lineone.net> Cc: <Scotch-Irish-L@rootsweb.com> Sent: Monday, December 12, 2005 12:33 AM Subject: Re: [Sc-Ir] Ludie question about Limestone > Hi, > Yes, Texas is infested with limestone layers and bluff and caves.
