I did not manage to chisel into James Rawson’s head, lots of tough rock there

We often think of palaeontology and religion as contradictory or opposites, especially when it comes to arguments about the age of the Earth, the origins of life & mankind, and drivers of evolution, so it is really special to see how these Lebanese fossils bridge the divide
In case you missed it! A 2nd fossil from the Upper Cretaceous of Lebanon has been gifted to the Vatican. This time directly to the Pope!
