A charming Simak novel. Light reading. Though published in 1978, it felt as if it was written in the fifties... Oh, that's probably because it is an expansion of a shorter work Simak wrote in 1955 entitled "Project Mastodon" (which can be read at This expanded version is actually a total rewrite but the spirit and style is still intact.

It is, for the most part, a story that explores all the commercial and social possibilities that come with the discovery

A charming wonderful tale of time travel. Simak's characters are always so engaging and full of life, it makes the simplest of them lovable and almost tangible -- even the strange entity that is Catface. The atmosphere of the storytelling is a bit simple yet is still one of wonder and of surprise. Despite the slight hint of greed, the bureacratic stubbornness of government, and the nonsense of religion, the issue of social responsibility that arises doesn't detract from the adventure. In all it' ...more

I like this book because it opened my mind (well it was already opened before that) to the idea of what the earth was like before us. These days there are plenty of books and videos discussing Life After Man, but how many to before? And in this book there is one paragraph that is my favorite, the opening paragraph in chapter 21:

"It was spring in Mastodonia and everything was beautiful. The mobile home stood on top of a little ridge no more than a half mile or so from where the time road brought
My father purchased a copy of this book for me when it was brand new in 1978, and I was five. I tried to read it then, but it was far, far above my head and I put it down. I read it entirely at the age of 12 in 1985, and enjoyed it then. The fact that Mastodonia was once a Science Fiction Book Club main selection inspired me to join the SFBC, a club to which I still belong, 26 years later.

Having lost my original copy in a house fire years ago, I obtained another copy via the internet for one cen

A lovely, gentle journey, well told and as with all of his books, with a love for his characters. Clifford Simak has a very easy writing style, which makes all of his works simply fly along as you read them, and he brings a real warmth to sci fi.
Uma ideia interessante, do Cheshire Cat alienígena q só de onda organiza uns wormholes temporais pro casal de quase arqueólogos.

Една прекрасна книга повдигаща много въпроси ... и една от първите не книги игри, които прочетох преди много много време.
review of
Clifford D. Simak's Mastodonia
by tENTATIVELY, a cONVENIENCE - May 17, 2013

I think this is the 1st Simak novel I've read, maybe I've read some short stories. It seems that he always struck me somehow as a 'generic' SF writer - not necessarily such a 'bad' thing, I'd rather read a 'generic' SF writer than a generic horror writer anyday. Nonetheless, something about his work, maybe the titles, put me off.

HOWEVER, reading this, I enjoyed it. At 1st, he seemed like a California SF writer
Good story idea, but I didn't find the way it unfolded believeable.
A distant ancestor to Jurassic Park. Interesting, though dated, sci fi. Gets a half-hearted recommendation from me--you could do worse. It'll kill a plane trip without killing brain cells. No, this isn't the most cogent review, but I just can't bring myself to spend a ton of time on it. That should tell you everything you need to know.
Though imperfect and dated, this book has charm: great atmospheric descriptions and an unforgettable character in Catface. True to classic SF, it believes in its own ridiculous big ideas strongly enough to summon fascination in the reader.

An old girlfriend steps out of Asa's past along with his dog. Asa starts trips in time as the woman starts thinking of a time travel business but soon problems arise as governments become involved.
Big game hunting for the wealthy. They exploit the past for safari expeditions with full governmental sanctions. Once more Simak posses questions of social responsibility.
Qualsiasi romanzo di C.D.Simak vale la pena. Questo anche di più. L'autore qui da fondo alla sua fantasia e passione per il Miocene ed i viaggi nel tempo.

This is a comic science fiction novel which I didn't find very funny.
