点评:We joined Oliver from Dinosaur Expeditions for a fossil-hunting trip along the beach at Brook Chine on a breezy evening in April. At £25 for my family and I, we were expecting a pleasant 2 hour walk during which we would pick up a few tips on what to look for. This was indeed the case, but with so much more. Oliver, our guide, met us in the carpark where he explained where we would be going and what to look for, bringing examples from his pockets to circulate amongst us in a slickly choreographed talk that quickly brought the group of about 20 of us up to speed.
Down on the beach we put our newly acquired skills to the test, quickly finding examples of fossilised wood and shelly limestone. One of our party was even eagle-eyed enough to spot a small fragment of dinosaur bone amongst the gravel. Oliver tried to manage our expectations by telling us this was an extremely rare find.
The walk continued to a spot where our guide paused to tell us about the geology in the cliffs. A muddy estuary some 120 million years ago (if I remember correctly!) was subject to a flash flood during which the imprints of dinosaur footprints were in-filled with sediment which hardened over time into rock. As the sea erodes the cliff, these casts fall into the beach. At this point Oliver tapped a nearby rock with his stick. It had three points to it and I realised with amazement that it was one of the footprints we'd been told about. Further rocks were identified as being from several different species as Oliver painted a scene of predator and prey captured in a snapshot of time by the flash flood.
It was a magical evening, far exceeding my expectations. My young family (9 & 12) were both engaged with the activity, finding fossils and asking questions, which Oliver answered with an inspiring authority.
This trip alone would have made our holiday on the island special and I cannot commend this company highly enough.
翻译:四月一个微风习习的傍晚,我们跟随恐龙探险公司的奥利弗,在布鲁克钦海滩进行了一次化石搜寻之旅。我和家人一共花了25英镑,原本以为会是一次轻松愉快的两小时漫步,期间还能学到一些寻找化石的技巧。事实的确如此,而且远超预期。我们的向导奥利弗在停车场与我们碰面,他详细地讲解了行程路线和需要寻找的化石,还从口袋里掏出一些化石样品,在大家之间传阅。他行云流水般的讲解,很快就让大约20人的团队迅速掌握了要领。
来到海滩,我们立刻实践了新学的技能,很快就找到了一些化石化的木头和贝壳状石灰岩。我们当中甚至有人眼尖,在砾石中发现了一小块恐龙骨头碎片。奥利弗提醒我们,这可是极其罕见的发现,让我们别抱太大期望。
我们继续前行,来到一处导游停下来讲解悬崖地质的地方。大约1.2亿年前(如果我没记错的话!),这里曾是一片泥泞的河口,遭遇了一场突发性洪水,恐龙的足迹被沉积物填满,这些沉积物随着时间的推移硬化成岩石。随着海水侵蚀悬崖,这些足迹最终落入海滩。这时,奥利弗用棍子敲了敲附近的一块石头。石头有三个尖角,我惊讶地发现,这正是我们之前听到的足迹之一。奥利弗还向我们描绘了一幅景象:洪水过后,捕食者和猎物在那一刻交织在一起,奥利弗辨认出其他几块石头属于不同的物种。
那是一个神奇的夜晚,远远超出了我的预期。我的两个孩子(9岁和12岁)都兴致勃勃地参与其中,寻找化石,并提出各种问题,奥利弗以令人信服的专业知识一一解答。
单凭这次旅行就足以让我们的岛屿假期变得格外难忘,我对这家公司赞不绝口。
