A reconstruction of Dilophosaurus wetherilli based on a study published at the beginning of this month of July 2020 in which the appearance of the crest of this animal is questioned, because although since 1954, based on the UCMP specimen 37302 described by paleontologist Samuel Paul Welles few specimens of the species have been described, the truth is that since in most cases these remains are fragmentary, and a complete skull has not been found to date, the shape of the skull has been misinterpreted so far. Mainly due to a small protruding part that was thought to be a point outside the ridge, according to this year's reconstruction based on the UCMP 77270 sample that shows that this structure was part of the complete ridge, which has made the authors of the study suggest Marsh A. and Rowe T. that this animal would have had a keratin-covered structure on the ridge, very similar to modern guinea fowl and cassowaries, who have a crested skull covered in keratin. Although the complete shape of the ridge is not known in the fossil record, this study proposes that it may have been larger than previously thought based on modern animals.
Only a finding of a complete skull will give us a better idea of the appearance of this animal.

Una reconstrucciуn de Dilophosaurus wetherilli basada en un estudio publicado a comienzos de este mes de julio de 2020 en el cual se cuestiona la apariencia de la cresta de este animal, pues si bien desde 1954 que en base al ejemplar UCMP 37302 descrito por el paleontуlogo Samuel Paul Welles se han descrito pocos ejemplares de la especie, lo cierto es que como en la mayorнa de los casos estos restos son fragmentarios, y no se ha encontrado un crбneo completo hasta la fecha, se ha malinterpretado hasta ahora la forma del mismo. Principalmente por una pequeсa parte sobresaliente que se pensaba era una punta fuera de la cresta, segъn la reconstrucciуn de este aсo en base al ejemplar UCMP 77270 demuestra que dicha estructura era parte de la cresta completa, lo que ha hecho sugerir a los autores del estudio Marsh A. y Rowe T. que este animal habrнa poseнdo una estructura cubierta de queratina sobre la cresta, muy similar a las gallinas de guinea y casuarios modernos, quienes poseen un crбneo crestado cubierto de queratina. Si bien la forma completa de la cresta no se conoce en el registro fуsil, este estudio propone que pudo haber sido mayor a lo que se pensaba basado en animales modernos.
Solo un hallazgo de un crбneo completo nos darб una mejor idea de la apariencia de este animal.
