Supposed fossil plant from Colombia actually a juvenile sea turtle
DD1991 posted a topic in Fossil News
A couple of fossils from the Early Cretaceous of Colombia originally classified as plants have been reidentified as juvenile sea turtle fossils: Fossil plant or turtle? (palaeo-electronica.org) Turns out a 100-million-year-old plant fossil was really a baby turtle (cosmosmagazine.com) Fossil first identified as plant is actually a baby turtle | Popular Science (popsci.com) The initial assignment of Sphenophyllum colombianum to Sphenophyllum by Huertas (2003) was perplexing because Sphenophyllum is known only from the late Devonian to Permian, but the reclassification of S. colombianum as a marine turtle removes the sole chronologically extraneous record of Sphenophyllum.

Hi all, I picked up a lot of partial ammonites and ammonite imprints on my latest fossil hunting trip. I was wondering if anyone may have an idea as to which types of ammonites I've come across. They come from the Paja formation in Colombia which is part of the Cretaceous. Thanks in advance
