This dinosaur taller both of us together.这句有错吗?

是的，这句话有语法错误。可以改为：

This dinosaur is taller than both of us together.

或者：

This dinosaur is taller than the two of us put together.

有错，缺少谓语和比较状语的连词。属于中式英语。正确的表达方式应该是：

This dinosaur is taller than both of us together.

这个问题非常简单，这句话肯定有错误，英语不是汉语的叠加，需要遵循一定的语法规范。
你想说这条恐龙比我们两个加起来还高，但是英语句子错了。
缺少比较词than，而且句子重复了。
正确的是This dinosaur is taller than both of us.

这句话有错，正确的句子应该是：This dinosaur is taller than both of us together.

有。1. 缺少谓语；2.比较级缺少关键词than
应该修改为：This dinosaur is （谓语）taller than both of us.
