| Large bodies helped extinct marine reptiles with long necks swim, new study finds Posted: 28 Apr 2022 09:54 AM PDT Scientists have discovered that body size is more important than body shape in determining the energy economy of swimming for aquatic animals. |
| A prehistoric forest grows in Brunei Posted: 28 Apr 2022 07:40 AM PDT A new study of leaf fossils conducted in the nation of Brunei on the island of Borneo has revealed that the current dominant tree group, the dipterocarps, has dominated the rainforests for at least four million years. The findings suggest that the current landscape is similar to what was present during the Pliocene Epoch, 5.3 to 2.6 million years ago, and may provide additional justification for conservation of these forests that support many critically endangered species. |
| Giant marine reptiles at 2,800 meters above sea level Posted: 28 Apr 2022 05:58 AM PDT More than 30 years ago, researchers discovered vertebrae, ribs and a tooth in the High Alps of eastern Switzerland. The typical shape indicated that they had to originate from large marine reptiles known as ichthyosaurs, but there was a lack of corresponding comparative material. A new study has now allowed a more precise classification. According to the findings, they belong to three different ichthyosaurs of around 15 to around 20 meters in length. The tooth is particularly unusual: With a root diameter of six centimeters, it is twice as large as the largest aquatic dinosaur tooth found to date. |
