一项新的研究发现,T. Rex花了35至40年的时间才成熟,比早先的估计要长得多。 A new study finds T. rex took 35–40 years to mature, much longer than earlier estimates.

对17个T. Rex化石进行的一项新研究显示,这些恐龙花了35到40年才完全成熟,远比以前认为的20年要长。 A new study of 17 T. rex fossils reveals these dinosaurs took 35 to 40 years to reach full maturity, far longer than the previously believed 20 years. 研究人员利用骨骼微结构分析,发现增长模式表明逐步发展,可能因环境、伤害或物种差异而有所变化。 Using bone microstructure analysis, researchers found growth patterns indicating gradual development, with some variation possibly due to environment, injury, or species differences. 根据跨极光成像和数学重建得出的研究结果表明,寿命至少为35-40年,质量为8.8吨或更多。 The findings, based on cross-polarized light imaging and mathematical reconstruction, suggest a lifespan of at least 35–40 years and a mass of 8.8 tons or more. 专家说,这项研究重塑了对恐龙生长的理解,并可能促使对其他物种的重新评价。 Experts say the study reshapes understanding of dinosaur growth and may prompt reevaluations of other species.
