8、rom under the seafloor off the coast ofAntarctica.In the sediment,they discovered forest material that was estimated to be about 90 million years old.At that period,dinosaurs were the ruler animals of the land.Johann Klages,a German geologist,was the lead writer of a study on the findings,published
9、in the journalNature.He said the sediment was collected from a depth of about 30 meters below the ocean floor.Klages said an examination showed that the material didnt form in the ocean.The researchers estimate that the area about 900 kilometers from the South Pole had average yearly temperatures of
10、 about12Cto13C.The soil included fine dirt particles and hard clay,as well as substances linked to at least 65 different kinds of plants,the study found.Although no animal remains were found,Klages said there were likely dinosaurs,flying reptiles and many insects in the environment.The research repr

17、 human watchfulness,which can delay an effective response.Most wildfires are reported by the general public,and other alerts come from routine foot patrols and watchtower observers.Passing planes and satellites also occasionally spot something,but“the fire first appears on the ground,Wang says.“When
18、 you see the fire from the sky,it is too late.”The team says its new sensor can be placed near tree trunks bases and send a wireless signal to a nearby receiver if there is a dramatic temperature increase.That heat also powers the sensor itself,without replacing batteries.The team printed the substa
