Is this the correct way to display dinosaurs at an indoor playground? I don't know who arranged them like this but... Is that an alternative way to dance a Sardana? Obviously a challenge with their short arms.. no judging here ;)

Llegint aquesta perla de @oscarandreu.bsky.social al tren, a més de 10,000km de #Catalunya, i de cop m'ha transportat en el temps i en l'espai. M'hi he sentit tan identificat 😂
Portada del llibre de Oscar Andreu, Manual de defensa del català.Cito "li pregunto al cambrer: «I al nen, ¿li podeu portar un suc de préssec?». I em contesta: «No tenemos. Pero tenemos de piña... y de melocotón».

How do exotic disease vectors arrive in new territories? Just like this. Took this picture in my local supermarket. Aedes mosquitoes, fruit flies, agricultural pests all exploit the same trade routes.
