Cabeça Dinossauro (Portuguese for Dinosaur Head) is the third studio album by Brazilian rock band Titãs, released on 25 June 1986.

[4] Vocalist Arnaldo Antunes and guitarist Tony Bellotto's arrest for drug possession in 1985 (and the former's subsequent three-year house arrest sentence[3]); the "relative failure" of previous album Televisão; and the will by the band to take a heavier direction influenced the music on this album.

"[5] The band was also looking to establish a clearer identity, something they hadn't achieved up until then with an unusual line-up of eight members, several vocalists and no crooner.

[14][2] The album's front and back covers were taken from sketches by Leonardo da Vinci:[15] "The Expression a howling Man" and "Grotesque Head", respectively.

Both acetates were brought straight outta Louvre by a friend of vocalist and keyboardist Sérgio Britto's father.

A gesture of generosity by André Midani, then president of Warner, which gave us total support before, during and after the recording sessions, complying with almost every of our requests.

[9] "Homem Primata" was released in 1987 as the sixth single by the band and it featured a reworked version of "Polícia" and a dance remix of the same song as B-sides.

Eventually, he would interrupt the show and say that wasn't music; he would then simulate an argument with Antunes and would join the band afterwards to resume the song.

[18] "O Quê" was the most demanding track in the album, according to Britto:[9] The arrangement totally changed and here Liminha had a decisive role: he programmed the electronic drums, he suggested the bass line, he played the guitar and had us perform an endless 'jam' over two days until we reached the final result.

That opened a new horizon for us and put us in contact with elements we would explore very much in the next years.In a 2016 interview, coproducer Pena Schmidt considered that "the mantric perfection of 'O Quê' paved the way for some three subsequent releases.

[21] In a 2012 interview, guitarist Tony Bellotto revealed he made a bet with vocalist Branco Mello: he would buy him a bottle of Jack Daniel's in case the album sold over 100,000 copies, since he thought it would be a commercial failure.

[19] In the Rio de Janeiro leg of the tour, the group couldn't find available venues and had to use the Teatro Carlos Gomes.

Only comparable to Õ Blésq Blom and Jesus não Tem Dentes no País dos Banguelas.

Despite that, I don't dare point any band that seems influenced by it.In 1997, Bizz magazine elected Cabeça Dinossauro as the best Brazilian pop rock album.

[25] In September 2012, it was elected by the audience of Radio Eldorado FM, of Estadao.com e of Caderno C2+Música (both the latter belong to newspaper O Estado de S. Paulo) as the seventh best Brazilian album ever.

[26] In 2012, in order to celebrate the band's 30th anniversary,[14] Cabeça Dinossauro was re-released, fully remastered and with a bonus disc containing the original demos for the songs, plus a previously unreleased track, "Vai pra Rua", an outtake of the album.

[27] In the next year, the remaining members of the band recorded a video for the title song, using images from the movie Vai que Dá Certo.

[27] Both the movie and the video feature Brazilian actors and humorists Fábio Porchat, Gregório Duvivier, Bruno Mazzeo, Lúcio Mauro Filho, Danton Mello e Natália Lage.

[1] In 2022, it was elected as one of the best Brazilian music albums of the last 40 years by a O Globo poll which involved 25 specialists, including Charles Gavin, Nelson Motta, and others.

Vidal considers that the sign in 1986 "provoked the urgency of living a newly-acquired liberty, with the end of the dictatorship, today [2016], it fights to guarantee such conquest, in a world scenery troubled by growing conservative forces.

[5] The book was released by publisher Tinta Negra, organized by André Tartarini and includes tales by authors such as Letícia Novaes, Juliana Frank and Renato Lemos, besides an introduction by Bellotto.
