I love digging in the back garden. Sometimes, I’d dig for pottery and stuff, but I’ve always wanted to find a fossil (化石). I like finding out about the past. At school, my favourite subject is history. I’ve been watching Andy’s Prehistoric Adventures since I was three. I knew I had a good chance of finding a fossil, because my house was built on a muddy, limestone substrate (石灰岩基质), in Walsall, which means millions of years ago, my garden wasn’t my garden at all—it was a coral reef (珊瑚礁).

On 22 March, it was a sunny day. I came back from school. I asked Dad if I could dig in my favourite spot by the yellow bush near our house, where we had planted potatoes and onions, but he told me not to, because he’d just moved a tree there and it was establishing roots. I went to the back garden instead, taking Dad’s old brown wooden garden tools. I dug a big hole, about a foot deep, which didn’t take very long, where I found a ball of mud with something pointy sticking out the top. I ran into the kitchen screaming. I was so excited. I knew it was a fossil.

At first, I thought it might be a deer’s tooth or a goat’s claw. When Dad washed the mud off, we saw that it had lots of bumpy, wavy lines; we both thought it looked like one of the sea anemones, from the fish tank in his office, but with a horn(触角). Dad sent a video to the Fossil Finds UK Facebook group. A man calling himself an archaeologist (考古学家) replied saying it had the markings of a horn coral from the Palaeozoic era, which is the very beginnings of life on Earth. I had found one of the oldest fossils in England.

We looked in my books and online for more information. We typed our postcode into a British Geology Survey search where you can find out what you’re standing on—ours is the oldest substrate in the area, with lots of clay and limestone, but it’s unusual to find anything so close to the surface. Experts told us that my horn coral lived between 415 million and 480 million years ago. There weren’t even proper fish or sharks then.

Before the horn coral, the only fossils I was familiar with were shark teeth that Dad got me.
