Death Throes
If you’ve looked at the articulated 150-million-year-old Archaeopteryx fossils, you probably have noticed that they all have a weirdly similar pose: their heads are thrown over their backs, mouths open and tail curved upwards. Scientists have been puzzled for years by what caused this distinctive pose, but now two paleontologists propose an explanation: this characteristic posture was the result of agonized death throes triggered by brain damage and suffocation.
