Ocean related fossils are something I'm relatively unfamiliar with, but I noticed this landscaping rock from Central Texas over the holidays that caught my eye. It didn't look to be the right material or texture for petrified wood. It reminded me of some of the coral pictures I've seen here. The rock was pulled from an area around the Hooper Formation I believe. The Wilcox Group. The rock is about two feet long by one foot wide. Could it be favosites?

Were there any giant sea snakes during the Paleocene?
Joseph Fossil posted a topic in General Fossil Discussion
I've been researching again large reptiles of the Paleocene (66.0-56.0 Million Years ago) and Eocene (56.0-33.9 Million Years ago) eras recently and I've come across something interesting - the sudden emergence of giant sea snakes in the Eocene. The Paleocene did see some large snakes, including the largest known snake in the fossil record the Boa relative Titanoboa (which grew up to 12.8-14.3 m. (42-47 feet) in length). But the sudden appearance of large sea snakes like Palaeophis colossaeus (which grew up to 12.3 m. (40 feet) in length) during the Eocene perplexes me as I've been struggling to find any large (or at least fairly large) sea snakes from the Paleocene. That is except one possible contender named Vialovophis from the late Paleocene as described in a Scientific Paper from 1997. https://www.researchgate.net/profile/Alexander-Averianov/publication/235806050_Paleogene_Sea_Snakes_from_the_Eastern_Part_of_Tethys/links/5437db850cf2027cbb205006/Paleogene-Sea-Snakes-from-the-Eastern-Part-of-Tethys.pdf I'm just a bit curious why this? Did these sea snakes evolve such gigantic sizes only during the Eocene and why?- 4 replies
