Dinosaur brains dating
It resembles a small dinosaur, but since flightless dinosaurs have been extinct for 65 million years, scientists have struggled to identify it.
The creature has now been sent for analysis, including carbon dating, which will reveal its age.
Else Marie Friis, lead author of the study and professor emerita at the Swedish Museum of Natural History, has analyzed some of these fossil remains of angiosperms — flowering plants — preserved in soils in Portugal and North America.
She and her colleagues used a relatively new visualization technique — synchrotron radiation X-ray tomographic microscopy (SRXTM), which allowed them to explore the delicate fossils without damaging or destroying them.
He said: 'It looks like a dinosaur, but we can't say anything until all the tests are done.'Aaryan Kumar, who is pursuing a Ph D in Paleontology from Delhi University, told local media that it was impossible for a dinosaur skeleton to be so well preserved after so long.They're all types of theropods, a suborder of dinosaurs that ranges in size from the mighty T Rex to the tiny Anchiornis.Dr Dhakate said the specimen had now been sent to Dr Bahadur Kotlia, a paleontologist at Kumaun University, for historical analysis.They imaged 250 seeds spanning 75 different species (some were also different genera), revealing the embryos and nutrient structures inside the seeds in exquisite detail.[Photos: Ancient Flowering Plant May Have Lived with Dinosaurs] Around half of the fossil seeds they examined contained preserved cell structures within their seed coats, and about 50 seeds held partial or complete embryos.
