这是教材上的句子。为什么不用dinosaurs, dinosaur 是可数名词,而且前面是different species.
还有一个
With the help of computer ... 这里computer 为什么既不加冠词又不变复数形式。

1.表示种类的词的用法:
以kind 为例
What kind of +名词单数
This kind of +单/复数名词 都可以.
所以你的那句话用复数也的正确的
2.第二句中的我也有疑问
发明类的词在语法中要求加the
Bell is considered to have invented the telephone in the world

用在“表示类型的名词%2Bof”这一结构的单数可数名词前,一般不加冠词。如:

Is this kind of radio made in China? 这种收音机是中国制造的吗?

因为,这里说的是恐龙的不同种类,只要在"种类"上变为复数即可.
这里的computer 特指电脑这种发明,就不要加冠词了.

There are many different species of dinosaur and all of them have been found in China.
用单数dinosaur或复数dinosaurs都可以.species像kind一样.例如:
different kinds of animal(animals)
各种不同种类的动物.
With the help of computer我认为用复数computers可以.例如:
With the help of my teacher(teachers),I have made great progress in my study.
