如何使用纯CSS创建以下箭头？

到目前为止,我有这个:

.halfCircleLeft{
    float:left;
    height:50px;
    width:40px;
    border-radius: 0 90px 90px 0;
    -moz-border-radius: 0 90px 90px 0;
    -webkit-border-radius:  0 90px 90px 0;
    background:green;
}

</div>

这是一个工作小提琴

或者更大的一个

<div class="HalfCircleLeft"></div>

.HalfCircleLeft
{
    margin: 100px;
    height: 100px;
    width: 50px;
    border-radius: 0 50px 50px 0;
    background-color: #cfa040;
    position: relative;
}

    .HalfCircleLeft:before
    {
        content: "";
        position: absolute;
        border-top: 10px solid transparent;
        border-bottom: 10px solid transparent;
        border-right: 10px solid black;
        top: 40px;
        left: 10px;
    }
        .HalfCircleLeft:after
    {
        content: "";
        position: absolute;
        border-top: 10px solid transparent;
        border-bottom: 10px solid transparent;
        border-right: 10px solid #cfa040;
        top: 40px;
        left: 13px;
    }
