| Abstract: | A new species of pterobranch has been found that has features that could resolve the longstanding arguments by palaeontologists about how the fossil graptolites produced their elaborate extra-corporeal homes. Many complex and biologically highly unlikely solutions previously proposed can be simplified. This animal is probably classifiable as a graptolite and thus a living fossil, representing a group thought to be extinct for 300 million years. |
