艾瑞龍屬(屬名:Arenysaurus)是鴨嘴龍科恐龍的一屬。化石是一個部分頭顱骨與身體骨骼,發現於西班牙庇里牛斯山脈,年代為白堊紀晚期(馬斯垂克階),約6600萬年前。

模式種阿氏艾瑞龍A. ardevoli),是在2009年由西班牙古生物學家Pereda-Suberbiola等人所敘述和命名。屬名是以化石發現處的阿倫(Arén)為名,一處人數約300人的小鎮,該地居民曾日以繼夜協助古生物學家挖掘化石;種名則是紀念地質學家Lluís Ardèvol。

艾瑞龍的身長估計為5到6公尺。艾瑞龍是種原始賴氏龍亞科,牠們是一群缺乏中空頭冠的鴨嘴龍類恐龍[1]。艾瑞龍是已知最完整的白堊紀晚期恐龍化石之一[2]

原始化石目前存放在阿倫鎮的地方博物館,並有化石挖掘過程的影片、重建模型[2]

Isaac Sweers Isaac Sweers (Nijmegen, 1 januari 1622 - 21 augustus 1673)[1] was een Nederlandse admiraal uit de 17e eeuw. Zijn familie Anders dan de meeste Nederlandse zeehelden was Sweers niet afkomstig uit een zeemansfamilie of zelfs maar een havenplaats. Zijn vroege leven is uitzonderlijk goed bekend doordat er een autobiografisch verslag door zijn familie is bewaard, waarin Sweers op ironische wijze zijn jeugd beschrijft. Hij werd op 1 januari 1622 geboren in Nijmegen en was de vij...
