The ‘Alien Goldfish’ Finds a Home 2022-09-20T04:00:00Z The researchers knew that surface temperatures rose about 10 degrees Celsius in the tropics because of previous scientific analysis of the fossilized teeth of eel-like creatures called conodonts. Global warming today mirrors conditions during Earth’s largest extinction event: UW study 2018-12-06T05:00:00Z Among vertebrates, the earliest mineralized tissue was found in the feeding apparatus of extinct jawless fishes, the conodonts. Elephant shark genome provides unique insights into gnathostome evolution 2014-01-08T18:21:42.027Z Past work examining how some conodonts grew the hard spurs in their mouths shows that it was startlingly similar to how modern animals grow teeth. Fossil Scans Reveal Origins of Teeth 2013-10-16T20:15:00.500Z It should be noted that our biostratigraphic dating is based on many more sample points than the isotope data points because not all samples yielded enough conodont material for oxygen isotope analysis. [Technical Response] Response to Comment on "Lethally Hot Temperatures During the Early Triassic Greenhouse" 2013-02-28T19:25:20.113Z That led scientists to conclude that Typhloesus had snacked on conodonts. The ‘Alien Goldfish’ Finds a Home 2022-09-20T04:00:00Z Using finite-element analysis -- a method commonly applied to model the effects of physical forces on airplanes -- the team then compared the conodont teeth with similarly sized bat molars. Jawless Vertebrate Had World's Sharpest Teeth 2012-03-15T01:15:00.213Z Using finite-element analysis — a method commonly applied to model the effects of physical forces on aeroplanes — the team then compared the conodont teeth with similarly sized bat molars. Jawless Vertebrate Had World's Sharpest Teeth 2012-03-15T00:15:00.200Z “While the later conodont tooth structures are absolutely indistinguishable from modern skeletal materials, our work shows they are not the same thing,” says Donoghue. Fossil Scans Reveal Origins of Teeth 2013-10-16T20:15:00.500Z At sea, 20% of all families abruptly disappear, including an entire class of creatures — the eel-shaped conodonts. Dark days of the Triassic: Lost world 2011-11-16T18:20:30.077Z At first we thought we were at a particularly nice rest-stop, but then we sighted the monuments to the conodonts. We Visit Fishy Relatives, Geology Wonderland 2011-06-23T14:45:00.457Z The team found that the conodonts did not process food using a mechanism based on muscular force, as mammals do. Jawless Vertebrate Had World's Sharpest Teeth 2012-03-15T01:15:00.213Z Sharp and specialized The team found that the conodonts did not process food using a mechanism based on muscular force, as mammals do. Jawless Vertebrate Had World's Sharpest Teeth 2012-03-15T00:15:00.200Z They report in Nature this week that the structures found in early conodonts evolved independently from vertebrate teeth. Fossil Scans Reveal Origins of Teeth 2013-10-16T20:15:00.500Z The latest work, he adds, “reveals conodonts’ independent lineage. Jawless Vertebrate Had World's Sharpest Teeth 2012-03-15T00:15:00.200Z The Permian which ended with the largest extinction in the history of life, is defined by the fossils found within, notably the conodonts.
