DinoDrone! Saintis Australia menggunakan UAV utk mengesan Kesan tapak2 Kaki DINOSAUR . . .

SEMASA Drone dan dinosaur mungkin kelihatan seperti sebuah gabungan mungkin, tetapi ahli-ahli sains di Australia menggunakan teknologi masa kini untuk mengesan jejak prasejarah. Cetakan diletakkan di Australia Barat kira-kira 130 juta tahun yang lalu.

Mengambil kesempatan daripada teknologi moden, sepasukan paleontologists dari Universiti Queensland menggunakan pesawat terbang rendah untuk mendapatkan pandangan trek mata burung dinosaur yang dipelihara dalam batu di hamparan 200 km daripada pantai Barat Kimberley. Sudut pandangan ini adalah sangat bermanfaat, sebagai jejak langkah yang sering tersembunyi oleh batu bergerigi dan oleh itu sukar untuk mengenal pasti.

Drones and dinosaurs may seem like an unlikely combination, but scientists in Australia are using present-day technology to track pre-historic footprints. The prints were laid in Western Australia about 130 million years ago.

Taking advantage of modern technology, a team of paleontologists from the University of Queensland is using low-flying drones to get a bird's eye view of dinosaur tracks which are preserved in stone in a 200km stretch of the West Kimberley coast. This vantage point is hugely beneficial, as the footsteps are often hidden by jagged rock and are therefore difficult to identify.

"Ia membolehkan kami untuk bangun di atas beberapa trek laman web yang lebih menarik, dan mendapatkan banyak rakaman video yang baik, yang benar-benar menarik, dan banyak bersenang-senang," ketua pasukan Steve Salisbury memberitahu Perbadanan Penyiaran Australia.

"It's allowing us to get up above some of the more interesting track sites, and get lots of good video footage, which is really exciting, and lots of fun,” team leader Steve Salisbury told the Australian Broadcasting Corporation.

Rakaman yang akan diproses melalui perisian, menyediakan penyelidik dengan imej 3D daripada laluan bagi sauropods, dan berpotensi theropods. Pelbagai jenis cetakan adalah mudah dikenali - sauropods ketinggalan cetakan bulat & theropods mencipta nama dengan burung-seperti, trek yang tiga berujung.

That footage will be processed through software, providing researchers with 3D imagery of the paths of sauropods, and potentially theropods. The different types of prints are easily distinguishable – sauropods left behind circular imprints and theropods made their mark with bird-like, three-toed tracks.

Tapak kaki fosil terbentang dari bandar pantai Broome kepada James Price Point, utara 60 km.

Walaupun sebahagian daripada trek dinosaur adalah yang terkenal, yang lain telah dirahsiakan oleh orang-orang dan ahli sains tempatan Orang Asli, yang takut ianya boleh dicuri atau dirosakkan. Kebimbangan itu tidak itu tidak wajar - satu cetak dinosaur telah digerudi daripada batu untuk dijual di pasaran gelap pada 1990-an.

The fossilized footprints stretch from the coastal town of Broome to James Price Point, 60km north.

Although some of the dinosaur tracks are well-known, others have been kept secret by local Aboriginal people and scientists, who feared they could be stolen or vandalized. Such concern wasn't unwarranted – one dinosaur print was drilled from rock to be sold on the black market in the 1990s.



Tapak kaki adalah sebahagian daripada mitologi rakyat tempatan Yawuru, yang mengatakan bahawa mereka berminat untuk mempunyai cetakan didokumenkan jika ia membawa kepada pengurusan yang lebih baik dan perlindungan.

Tetapi sebahagian daripada trek yang ditemui buat kali pertama, berjuta-juta tahun selepas ianya telah terletak.

"Terdapat beberapa yang baru yang telah muncul dalam perjalanan ini, dan kadang-kadang ia hanya fikiran-bertiup betapa banyak terdapat dokumennya," kata Salisbury.

The footprints are part of the mythology of the local Yawuru people, who say they are keen to have the prints documented if it leads to better management and protection.

But some of the tracks are being discovered for the very first time, millions of years after they were laid.

"There are a couple of new ones that have emerged on this trip, and sometimes it's just mind-blowing just how much there is to document," Salisbury said.



Tetapi terdapat lebih kepada dokumentasi daripada satu mungkin terfikir. Pasukan itu mempunyai untuk berperang dengan air pasang besar di kawasan ini, yang menghakis tapak kaki dan apabila menentukan para saintis boleh bekerja.

Malah, Salisbury berkata beberapa kawasan terdedah hanya untuk beberapa jam, beberapa hari setahun.

But there's more to the documentation than one might think. The team has to battle with the area's enormous tides, which erode footprints and dictate when scientists can work.

In fact, Salisbury says some of the areas are exposed for just a few hours, a few days a year.

"Kami tidak mendapat banyak peluang," katanya awal bulan ini.

Penggunaan Drone adalah sebahagian daripada yang dibiayai kerajaan projek 'Berjalan dengan Dinosaur dalam Kimberley', yang dijadualkan untuk menyelesaikan menjelang akhir 2016.

“We don’t get many chances,” he said earlier this month.

The drone usage is part of the government-funded 'Walking with Dinosaurs in the Kimberley' project, which is scheduled to wrap up by the end of 2016.
