摘要

描述

Eubrontes, a footprint of a theropod dinosaur, preserved in reddish sandstones of the Moenave Formation (Lower Jurassic), near Tuba City, north of Flagstaff, Arizona.[1] Scale: The coin is a US quarter dollar (25¢, diameter: 24.26 mm, 0.955 in) comparable in size to a 50 euro cent coin. Hence, the maximum width of the footprint is about 30 cm (1 ft).

  1. see pictures at dinodomain.com at the Wayback Machine; Note: The whole domain is for sale now and there was only one picture of the original webpage archived, but it clearly shows the imprint in question, inferrable from the adjacent surface features of the rock.

该图像以硬币来表示大小。

应避免使用硬币来表示物体的大小。因为不熟悉该硬币的人必须费工夫去查询该硬币的大小,甚至依靠猜测,这与使用硬币的初衷不符。硬币也可能会增加地域偏见,并且某些硬币的图案还可能受到著作权保护。

理想状态下,照片中在物体旁应该有一把尺子或其他非硬币的物品(例如这张照片这张照片),或者用图像编辑器标记上一个刻度(例如这张照片这张图像)。国际单位制(公制)在全球范围内最为常用(参见厘米)。
