a bit rude to call them a monster, they're just weird, ok?

Nicknamed the "Y animal" or "wye", Escumasia roryi is an enigmatic fossil organism known from the Late Carboniferous Mazon Creek fossil beds in Illinois, USA, dating to about 308 million years ago.

Growing up to around 15cm tall (~6") this strange soft-bodied creature was Y-shaped, with two slender "arms" on each side of an apparent mouth opening, a flattened sac-like body with another opening on one side, and a long stalk ending in an attachment disc. Some specimens have uneven arm lengths, which may indicate damage from predation.

Being only known from the exceptional preservation conditions of Mazon Creek, and with nothing else quite like it in the known fossil record, Escumasia's evolutionary relationships are still a mystery. It's been tentatively linked to cnidarians – but this doesn't really fit based on its anatomy, and little further study has been done on it since its discovery in the 1970s.

It was probably a filter feeder, living attached to the seafloor and capturing suspended organic material or small planktonic prey with its arms. The environment it inhabited was a shallow tropical marine bay, located close to the equator at the time, near a large river delta that would have made the surrounding waters rather brackish. This ecosystem was dominated by cnidarians, particularly the anemone Essexella, along with various arthropods, lobopodians, polychaete worms, molluscs, echinoderms, fish, lampreys, hagfish, and other difficult-to-classify weirdos like the famous "Tully monster" Tullimonstrum.

"Mi Persona Favorita"

En esta Navidad quiero recordarte cuánto significas para mí y lo mucho que te quiero.

Estos tres meses desde que nos conocimos han sido, sin duda, los más bonitos de este año un poco o muy extraño que hemos vivido. Cada día que compartimos reafirma cuánto te valoro, lo importante que eres en mi vida, y que eres mi persona favorita en el mundo mundial.

Sé que estás atravesando una situación complicada, y aunque eso no deje de preocuparme, más allá de lo que sienta, mi mayor deseo es tu felicidad, porque tu bienestar siempre será mi prioridad.

Si pudiera gritarle al mundo entero cuánto te quiero y caminar contigo sin miedos ni presiones, lo haría sin dudar. Pero entiendo que quizás aún no sea el momento, y por eso seré paciente, dispuesto a esperar a que las cosas sucedan cuando deban suceder. Después de todo, los lazos más puros y hermosos florecen en silencio, lejos del ruido y del alarde, donde solo importan los corazones que los viven.

Pase lo que pase, aquí estaré para ti, como ese refugio en los momentos difíciles, la mano que te ayude a levantarte, y la persona que logre robarte una sonrisa incluso en medio de las tormentas. No importa cuán oscura sea la noche, prometo ser tu guía, tu apoyo, y también tu cómplice, sobretodo de esos momentos que solo tú y yo sabemos, y que recordamos y atesoramos con alegría y dulzura, esos segundos y ahora minutos donde se paraliza el tiempo y espacio.

Te quiero más de lo que las palabras pueden expresar, y deseo de todo corazón que todos tus sueños se hagan realidad, porque no hay nadie más merecedora de verlos cumplidos que tú, ya que eres maravillosa. Mi cariño por ti es infinito, y aunque el destino nos juegue las cartas como quiera, siempre te pensaré como mi compañera de vida.

¡Feliz Navidad, mi persona! Siempre contigo.

Atte.,

A.P.A.E.

So, incertae sedis is Latin for “of uncertain placement” and scientists use it to indicate they don’t know what higher classification to put a species in. But what I did not know is that one could also use the word problematica to mean the same thing and sound 100x more fun and cool.

E se le persone fossero troppo impegnate per pensare a te?E se chi resta non sapesse perché stai male e quindi non sapesse come aiutarti? In quei momenti sei sola. Di nuovo sola. Non solo ti senti sola, ma ti senti anche in colpa perché sei convinta di disturbare le persone le quali credi ti potrebbero aiutare, mentre loro pensano a cose ben più importanti. Vorresti urlare e piangere, ma non ce…
